Hello.
You can call me iExpress.
I have randomly found out that the act of trying to create a sentient entity with your mind is actually a thing and therefore, I'm finally here to share my two bits.
For the past few months, starting with minor depression, I've been occasionally feeling the presence of a friend - apparently, a tulpa, as you call it - I have already named, that spawned from my mind. I had no idea this was a practice among people, until I jokingly suggested someone to simply imagine their fangirling material next to them, and the asked me if I implied "tulpamancy". Some Googling later, I ended up here.
I try avoiding reading the guides as the means of help, as the process of bringing my tulpa to life, so to speak, is something I decided to find quite personal and unique to each person and think that guides would only end up frustrating me.
The thought of creating a tulpa to the degree in which they would be able to communicate and be apparent to me is something I find absolutely breathtaking and exciting. I'm pretty excited now that I know there's a community of people I can actually take with about this strange phenomenon.
Hopefully we'll get along.
