So I read some stuff about this, thought it sounded interesting and I've decided to make my own Tulpa. I mean, at the very least, it's a good way to get in touch with your subconscious (which is basically what a Tulpa is, I guess, lol) I started, with imagining the orb and adding traits, talking to her (I based the Tulpa off of Rainbow Dash, but slightly different personality, and she's allowed to deviate) and such. On the first session, I got the tingle in the back of my neck that everyone talks about, and I considered it a success. Then I pretty much got up to take a shower when I started getting second thoughts about the whole 'Tulpa' thing. Like, I didn't want to loose my grip on reality or anything, so I decided that I would do one more Tulpa-forcing session that day and if nothing happened besides the tingle, I would leave the whole thing alone and never speak of it again.
I did basically what I did the first time, telling her about her own traits and personality and such. However, I had never given her access to my thoughts before that point. I thought it would probably be a good idea to do so, and I thought that it was probably a good idea to break it to her that she's based off of a cartoon character. Basically, I did just that, however, I stressed to her that this did not mean that she WAS the character, and she is allowed to deviate from it however she liked. At this point, I started crying uncontrollably without warning, but I wasn't sad myself. I realized that she was obviously sad about basically being a fictional character, and was trying to communicate with emotions. I felt sorry for her, and in my mind, I imagined myself giving the orb of light (her) a hug. I told her it was alright, and it's okay if she deviates because I'll be satisfied with whoever she turns out to be and she'll always be apart of me. Then the crying immediately stopped and I swear to God I heard a 'thank you' in the distance.
Now I don't have the heart to abandon the Tulpa because I just realized that... this is a real whole other person I'm growing in my mind. It's pretty profound once you think about it, lol
