These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: LSD Dream Emulator
Demonic Spiders: There are things you could call enemies in the game, although you can't fight them and they just end the dream early. They all count as this, since most of them come out of nowhere, are hard to dodge, and scare the pants off you. And then there's the Bridge Guard, who looks like Satan.
Fan Nickname: Pretty much everything, from the Gray Man to the Violence District.
Hell Is That Noise: Any of the badly-synthed, trumpeting noises made by the wandering residents of the game. Also, the slow footsteps of the Gray Man, even though his feet don't move.
Most Annoying Sound: The game has some spectacularly crappy audio, especially the deafening footsteps of...the player.
Nightmare Fuel: Violence City, aka Violence District. Just...that place.
To clarify, there're severed limbs in the trash cans, women hanging from streetlamps who fall on you, several crazy residents, including one who shoots you (with an absurdly slow bullet), creepy letters or words written in blood, and most of the ways to die in the game.
What about the Abyss Demon? A huge Satan-looking demon who pops up from the edges of the cliffs in the Overworld.
And what about the huge freaking purple sun with a face on the prism-y bridge? That sometimes appears to be also behind you?
The Giant, who sometimes appears in the room directly to the right of the one you start out it.
The Nodding Men, who are sometimes in the ponds in Kyoto.
Certain textures that have eyes or faces on them.
The Kanji Faces, who appear mainly in Kyoto to spit kanji at you and fly away.
The Spectres, who appear at the base of the hotel where you start out.
The Teddy Bear in the hotel, who tries to hug you and follows you as long as you remain there. And who's standing watching a blood-splattered TV that kinda looks like Uboa of Yume Nikki.
It's safe to say that 99.9999% of this game is the very incarnate of this Trope just because it's all so weird.
True Art Is Incomprehensible: Most, if not all, of the noninteractive video dreams seem to fall under this...unless anyone else can figure out the meaning behind watching a kid eating, a goldfish bowl sitting in an elevator, a montage of Russian stamps, and pigeons sitting on ledges, flying, and walking around. It's likely that this is entirely intentional, considering how little sense most people's dreams seem to make.
