r/Tulpas started as a place to discuss a technique of self induced plurality that was based on Buddhism and Tibetan teachings.

Now you have a mentally unstable mod who has 7 or so imaginary friends and they are married and have children with each other. That mod bans anyone who suggests that is not true. Other people say they are not single but in relationships with imaginary friends and planning to marry them. Some people who've had 5-10 imaginary friends for just a few months say they are all sentient and that they are in committed romantic relationships with them.

Truly truly a toxic place that totally lost its purpose. I can't even blame anyone those who say Tulpamancy is mental illness if all you do is read that place. The mentally ill people there who want to justify it by saying it's all subjective is plain sad.
