Long time lurker because this subreddit fascinates and scares me.

Average r/tulpas user-post: "This is my tulpa, Konichi-chan! S/he's a 7' tall dragon ninja with a huge cock that I fuck every night. Also, I want to permanently swap with them because my life is not worth living. Also, I'm creating a harem of tulpas to have orgies with."

Get help, please get help. This isn't normal, there may be a valid reason of research the titillating concept of a "tulpa" -- perhaps as a form of meditation or as some sort of helpful "thoughform" to organize thoughts and/or emotions -- but teenagers creating sentient, imaginary sex slaves isn't one of them.
