"A tulpa is a thought-form: a manifestation of intent in human form of our imagination... Once the tulpa is endowed with enough vitality to be capable of playing the part of a real being, it tends to free itself from its makers' control. Tibetan magicians also relate cases in which the tulpa is sent to fulfill a mission, but does not come back and pursues its peregrinations as a half-conscious, dangerously mischievous puppet."
Alexandra David-Neel, Doktor Sleepless

A tulpa, also known as a thoughtform, is an independent entity brought into being by the power of belief. It starts out as an imaginary friend and gains sentience of its own, carries on a life independent of its creator, can be seen and heard by others, and can affect the world around them. It may come about accidentally, by someone who doesn't realize their Reality Warper powers, or may be created intentionally by one or more people with the hope of it becoming real in order to do things the creator couldn't. That's how some media and entertainment take it, anyways. The more humble fact is that they cannot affect anything outside its creator's mind. Moreover, they're usually close to what the creator intends it to be: a mostly friendly personality to act as a lifelong companion.

The word comes from certain branches of Buddhism, in which a tulpa is an object (usually a living creature) which is brought into existence by sheer will and concentration. In internet culture, a tulpa is part of a belief system in which people intentionally treat their imaginary friends as sentient beings.

In fiction, tulpas tend to be Always Chaotic Evil and turn on their creator, though many happy subversions exist.

See also The Power of Creation, Living Dream (possible supertrope), and Gods Need Prayer Badly. Contrast Not-So-Imaginary Friend, in which someone is mistaken for imaginary; Enemy Without, in which the being is closer to its originator than a spirit; Self-Constructed Being, in which the entity isn't necessarily being "born" in the sense of constructing its own identity in the process.

  • In Hogfather, there is so much spare belief floating around while The Hogfather is indisposed that it causes a variety of gnomes, bizarre creatures (such as an Eater Of Socks and a Hair Loss Fairy), and lesser gods (like the Oh God of Hangovers) to pop into existence as independent entities. They last only until The Hogfather is restored, except perhaps for the Oh God of Hangovers whose girlfriend, Violet, might just have enough belief in him by herself to keep him around.

After gaining sentience, they develop a bond with their host that is very similar to that of a creator and a Tulpa.

  • The Buffy the Vampire Slayer novel Go Ask Malice, which tells of Slayer Faith Lehane's background before coming to Sunnydale, reveals that one of her ex-boyfriends (Kenny, the "drummer" mentioned in the episode Revelations) from Boston had the power to create tulpas. His powers proved critical to enabling Faith's childhood "invisible friend" Alexandra (really the spirit of a long-dead vengeance demon, the "Malice" of the title) to regain some of her powers and in turn enable the spirit of her mother Artemia, a Slayer from ancient Greece, to act through Faith and drive her towards a clash with the vampire Kakistos, who had been responsible for Artemia's death. While they proved useful in that case, Kenny's powers were ultimately the cause of his break-up with Faith though, as she dumped him after she caught him in bed with a tulpa of his ex-girlfriend Andra.

  • According to some theories, the existence of the character Maria in Silent Hill 2 can be explained by this concept as an eroticized manifestation of James’ deceased wife. She is briefly playable during the Born From A Wish segment included in the re-released Silent Hill 2:Restless Dreams – the title of which itself is suggestive that she was literally conceived from James’ unconscious desires, specifically his repressed sexual desire concerning his late wife Mary during the progression of her disease. Although Maria physically resembles Mary, their personalities differ starkly, and throughout the game, Maria makes numerous attempts to delineate her individuality and differentiate herself from Mary before James, who is consistently unable to distinguish the two.

  • In The Sims 3, a young sim may receive a stuffed doll in the mail as a birthday gift. At first, it is an ordinary doll, but as the sim grows attached to it, the doll will eventually turn into an imaginary friend that only the sim can see.

  • Tulpas appear in New Vindicators, usually created by powerfully willed, creative people. For example, the mythical Spring-Heeled Jack is a tulpa, created by Charles Dickens, and was known in fiction as the Artful Dodger. Others include the 'ghost' of Psion, an Esper whose body is killed but whose mind and powers live on for a time, and a few more who might not last as long.
  • Some theorize that the Slender Man is this - the more you view his videos and believe, the stronger his influence reaches... Explored further in certain Slender Man works which seem to suggest the reason his powers are so incredibly capricious and inconsistent is because everyone has a different idea of what exactly his 'style' is. One noticeable point this was explored was when a large group of bloggers attempted to all write fictional stories detailing them all wounding the Slender Man, in hopes this would cause him to be wounded in real life. It didn't work.

  • South Park's Mega Crossover "Imaginationland" had the eternal war between fictional good guys and bad guys boil over into South Park's reality - this includes anything from children's show characters, to movie stars, to religious icons. As always, there was an analogy/moral beneath all of it - even if it only exists in people's heads, it becomes real by way of shaping people's thoughts and actions, religion and so on included.
