ELI5: Explain Like I'm 5

Tulpa

A tulpa is kind of like an imaginary friend that you can create in your mind and talk to. It’s like you’re daydreaming but with a specific person or character in mind. You think of the tulpa as if it were a real person, and talk to it like you would a friend, and the more you interact with it the more real it becomes. Some people even give their tulpas special skills or personalities so it’s like having another person in your head!
