Nancy: What I learned in the dream clinic. That's what I'm trying to prove, mother. Rod didn't kill Tina and he didn't hang himself. There's this guy. He's after us in our dreams.Sometimes, in fiction, the dreamer isn't the only one seeing his or her dream. Sometimes another character sees the dream or can enter it and become part of it. Sometimes it's played straight, other times for laughs, with a statement like, "Hey, this is my dream!" or "Hey, it's your dream." Sometimes characters able to do this for malevolent reasons, seeking to terrify and/or harm the dreamer for their own purposes like Freddy Krueger; others devote their abilities to protect dreamers from such threats like Doctor Strange. Compare/contrast Dream Weaver and Dream Stealer, which can overlap. Dream Weaver can be a subtrope at times. Not to be confused with Dream Spying. See also Talking in Your Dreams.

Anime and Manga
- In X/1999, Hinoto's sister Kanoe is more of this than a Dream Weaver (save for the TV series). Also Hokuto Sumeragi straddles the line: she can enter other people's dreams, alright, but has very few actual influence on them and can only do it when she herself is asleep, while the others can do it when awake too.
- Paprika, based on the Japanese novel of the same name.
- The New Universe character Nightmask has this as his superpower.
- Rising Stars: One person has this power.
- The Sandman: In "Sandman: The Doll's House", Rose Walker can do this during her brief time as a dream vortex.
- Dream himself can also do this, of course (being the Anthropomorphic Personification of dreaming) and regularly uses this ability throughout the series. Special note must be made of the time he hijacked a car that was being used as the set for an Erotic Dream and drove to London in it.
- Ramona Flowers from Scott Pilgrim.
- A little-seen mutant in the X-Men comics named Rem-Ram has this as his power, as a sort of telepathy which works only on the sleeping. He can contact the mind of a person who is awake, but that causes him severe pain and possible neurological injury.
- Doctor Strange has occasionally entered the dreams of clients to help them. His enemy, Nightmare, can control dreams and gain power through them.

- Plot of the movie Dreamscape
- Inception is all about entering and messing with peoples' dreams.
- The Matrix is a variant on this.

- Caspian is quite the dream walker early on in Astral Dawn. Caspian literally walks through his dream on a bridge made of glass within a cloud where he soon meets Ixchel, the Mayan goddess of the moon. Caspian later follows her beyond the mortal plane into the astral plane, taking his dream sequence to an unprecedented level.

- Warrior Cats Jayfeather has the ability to enter other cats' dreams, as do the members of Star Clan.
- In The Wheel of Time, Dreamwalkers can, among many other things, visit the dreams of others if they are so inclined. However, they are generally careful not to as once inside the dream they are subject to the dreamer's will and may be unable to escape. Also, if a Dreamwalker feels intense love or hatred for a given individual, they may be drawn into that person's dreams. Dreamwalkers spend most of their time in the Dream World.
- The Japanese novel Paprika, and the anime film based on it.
- In Rachel Griffin, classmate Zoe has the power to enter people's dreams as well as travel to their physical location, a useful talent if someone is possessed: she can Flash Step up behind them and belt them with a war club.

- Adrian Ivashkov from Vampire Academy visits the dreams of other people.
- Roswell: Isabel has this ability, she seems to need a photo of the person to touch to be able to do this. Whether this is actually needed, or just because Isabel hasn't had proper training in the techniques is not clear. In the books that inspired the series, all the aliens can do this, and they can also bring humans into other people's dreams by holding their hand while they enter the dream.
- Angels can enter dreams to speak with the dreamer and deliver messages if they need to. This is sometimes the only way angels can communicate with Sam and Dean who are often warded against (via hex bags) or physically marked against (via writing etched onto their ribs by Castiel) angels finding them personally.
- Played for Laughs when Fallen Angel Anna walks in on an Erotic Dream Dean is having (involving two strippers in angel and devil costumes) much to his embarrassment.
- Azazel, the yellow-eyed demon, is also shown to be able to communicate with people this way, though he can sometimes also influence the dream.
- In David Byrne's song "The Dream Police", there's an entire justice system to prosecute crimes committed in sleep.
Everyone has the same dreams, on different days of the week.
We are the watchdogs of your mind, we are the dream police.
- Angels of Blandine (Archangel of Dreams) and demons of Beleth (Demon Princess of Nightmares) in In Nomine do this as a matter of course, it's also possible for others to learn to do it.
- Dungeons & Dragons: The 3.5th edition supplement book Heroes of Horror supplied ideas and optional rules to create dream (or nightmare)-like sessions. This includes purposeful or accidental entry of a dreamworld from the waking world. It's only natural that it also featured certain feats based on interpreting and entering the dreams of others, called Oneiromancery.
- Sosunov magic in Chuubo's Marvelous Wish-Granting Engine is focused around dreams, including the option of walking into one to communicate with people or defend them from Outside-spawned dream horrors. The Dream-Witch character is also capable of this, despite not being a Sosunov or, for that matter, human (technically speaking).
- The title character of Alundra, as well as Meia, has this as their main power and use it to free people from the nightmares created by various dream demons.
- Final Fantasy VII has a segment where Tifa dreamwalks inside Cloud's dream.
- Wild Arms
- In Wild ARMs 1, Cecilia was able to dream walk once in order to battle a dream demon named Elizabeth who had been keeping Rudy trapped in his dreams.
- Wild ARMs 3 has The Saint who appears in the dreams of the leader of the Arc of Destiny, as well as the Dream Child from Shane's dreams. In reality, they're both the Dream Demon Beatrice, using her dream walking powers to manipulate people for her ultimate goal of creating a Filgaia where she could live in.
- In Wild ARMs 4, the seller of the Black Market is implied to be a dream demon, with one of the NPCs in the city receiving nightly visits in his dreams by someone who tells him to go buy stuff from the Black Market. This would certainly explain why the Black Market deals in levels rather than money.
- MARDEK had a dream reality in Chapter 3. It's not exactly walking through someone's mind, but it's shaped by human thoughts.
- Entering other characters dreams is required at certain points in the Neverwinter Nights 2 expansion pack, Mask of the Betrayer. The shaman Gannayev-of-Dreams has this power innately, and One-of-Many can learn to do this, depending on the player's actions.
- The Dream Machine includes the main character, Victor, and his landlord, Mr. Morton, and the machine itself.
- In Dragon Age, the Fade is where all races (barring the Dwarves) go when they sleep, though only Mages are capable of remaining self-aware whilst in the dreamworld. Because of this unique ability, they developed certain magical rituals involving lyrium, allowing them to enter the Fade whilst awake, enter another person's dreams, or allow them to release people from demonic possession, by attacking the demon at the source. Mages who attain full Dream Weaver status are known as "somniari" to the elves, though those are incredibly rare.
- Dragon Age: Inquisition has Solas, an expert on the Fade who regularly visits it just to hang out with spirits. He doesn't appear to be a Somniari, but can still communicate with others via their dreams.
- Physically entering the Fade, as opposed to lucid dreaming, is nigh impossible without extremely potent magic such as the Eluvians and the Anchor.
- This is the main gameplay gimmick of Mario & Luigi: Dream Team. Pi'illo Island has many magical pillows on which Luigi can fall asleep, creating a portal to the Dream World that Mario can enter. It's not just Luigi's dreams you can enter either. If you fall asleep next to someone, you end up in the same Dream World as them. Hence how you get to enter Big Massif's dream in Wakeport and Bowser's Dream in the final dungeon.
- If a Sburb player's dream body is dead, then any time they sleep, their consciousness travels to the Dreambubbles in the Furthest Ring. This shared dreamscape also doubles as the afterlife for Sburb players—from every parallel timeline in existence. That makes a lot of folks capable of stepping into one's dreambubble.
- Wayward Vagabond is not a Sburb player, so he gets normal dreams when he sleeps. Somehow, god-tier Vriska Serket was able to jump into one of his dreams and talk to him (in Morse code) anyway. It probably has something to do with Vriska's psychic mind-control powers.
- An example appears starting here in The Mansion of E, though it's not clear who exactly is doing the walking.
- In El Goonish Shive, a wizard enters Grace's dreams repeatedly in order to deliver an important message.
- The Aladdin episode "As the Netherworld Turns" had Abu and Iago use an enchanted crystal that appears to grant them the power to walk through walls, but actually sends them to the Netherworld. This is a big problem, because due to their intangibility, Aladdin and the others cannot see or hear them. Fortunately, with the help of Sultan's late father, who still haunts the palace, Iago and Abu learn that the only way to communicate to Aladdin and the others is to enter their dreams while they sleep.
- American Dragon Jake Long had an episode where Jake was in the dream realm thanks to a magical relic. He initially used it to date Rose while the two were forced apart. Then he wandered to other dreams, depicted as doors in a hallway.
- Jackie Chan Adventures: The talisman of Astral Projection, which lets one leave his body and become a spirit, also lets one enter dreams, which comes in handy several times on Jackie's adventures.

- In Danny Phantom, Danny discovers during season 3 he can overshadow (possess) a person to enter their dreams, while battling a ghost who want to feed off dreams for power.
- Princess Luna from My Little Pony: Friendship Is Magic:
- First shown in the episode "Sleepless in Ponyville". One of the duties of being Princess of the Night is to protect sleeping ponies from their nightmares and to help them face their true fears that are causing the nightmares.
- In "For Whom the Sweetie Belle Toils" Princess Luna is able not only to enter a pony's dream, but redirect it to help them learn An Aesop.
- In "Bloom and Gloom" Luna escorts a dreaming Apple Bloom into other ponies' dreams, showing her that her friends are experiencing the same fears that prompted her own nightmares.

- Justice League, "Only a Dream", Martian Manhunter can enter people's sleeping minds.
- Bill Cipher of Gravity Falls is implied to be one- whenever he appears before someone, the surroundings turn black and white, and when he leaves, people act like they've come out of a trance. Also, if you look closely, an entry in one of the journals on Bill claims that he's appeared in the author's dreams.
- In ''The Big Snooze'' Elmer Fudd has quit his position as Bugs' patsy and takes a nap, dreaming sweet dreams. Bugs decides to get in on it, goes to sleep, and enters Elmer's dream, turning it into a wacky, loud nightmare.
- One Rick and Morty episode had Rick and Morty go into Morty's math teacher's dream. The results are... bizarre, to say the least.
- In the Poet Anderson: The Dream Walker short film, all dreams play out within the Dream World, which means that Dream Walkers can be involved with the affairs of other Dream Walkers. However, threats specific to one Dream Walker, such as Poet's Night Terror, can't be confronted by other Dream Walkers.
- The definition of a Dream Walker in the short film and the comics is different from here, treating a Dream Walker as a Guardian type Lucid Dreamer.
- As shown on Livescience and in the journal Science, progress is being made on the decoding and imaging of dreams.
- A recurring notion in mysticism is that two people can and will share a dream if they are sufficiently connected, ideally emotionally so, in real life. The kicker is that the active dream world, the "Astral Plane" of the mystics, stands outside time and space. Just because Bob dreamt that Alice entered his dream and they interacted in a "real life" sort of way does not mean that they both had the same shared dream on the same night. Alice might remember having that dream ten years ago - or she may not have it for another twenty years. Illuminatus! creators Bob Shea and Robert Anton Wilson described dreamspace as the MorgensHeuteGesternewelt - the "tomorrow-today-yesterday world".
