Tulpas are super imaginary friends, they're an interesting concept and since I've always been a bit of an outcast I decided to try out it a few years ago. 

I remember following a guide that I found very deep in an internet forum that I probably wouldn't be able to find these days. It consisted in feeding 'energy' to an entity inside my mind, and working through meditation into creating a consciousness besides mine. After that I started giving it shape, personality and looks. My tulpa would've been a redheaded girl with a beanie.

A fair warning from the guide was not having ill intent whilst creating the tulpa, you can't make it with the intentions of having tulpa-sex with it (something that is far too common) and if you're depressed or have a lot of self-hatred, the tulpa could antagonize you eventually.

In the end I decided not to continue because I was indeed a very depressed person at the time, however even though I didn't give the tulpa any shape, looks or personality, I can still feel the 'other' consciousness inside of me. And even to this day I feel like I could start shaping it again, it's weird. 

Some say it's like self-induced schizophrenia, maybe you shouldn't try out.

You should either finish making it or suck the rest or the energy you put in that thing out
