>Now that I think about it, because there was continuity of self and of memory, I think I just swapped egos.
This might be closer to what happened. Do you feel like a different person? Or is it just the manifestations of your personhood that are different, your actions and habits

Anon is right. From a slightly different perspective, creating a tulpa is like creating a partition in your brain for a tandem personality circuit in the parts of your brain's neurocircuitry that handle personality.

A tulpa, all personality really, is fundamentally a collection of ideas built from sense impressions, and, to 's point, behavioral heuristics built from those. Personality being largely one's projected image and behavior. All 'people' are technically tulpas, structurally. Everyone you've ever met is this kind of sensory memory processor and behavioral output algorithm/mechanism, it is how persona is made. 

Most people don't really get into it, they think of themselves as themselves and never invite anyone else 'upstairs,' as it were. When you're creating a tulpa, you're writing a new persona and a new person. Like an AI, as the persona is developed more thinking about it and interacting with it (making or reinforcing neural connections, 'writing new code'), as it is integrated into more of your neural systems, as your understanding and concept of them become clearer and they internalize it, they can become self aware, intelligent, able to see and sense the world through your body like you do. They can understand things on their own, maybe even hide things from you (maybe). They can share memories, and your imagination with you, they can imagine things on their own.

It's true, you can use the same process to overwrite your original ego with a new one of your design, become a new person. That said, a developed enough tulpa IS like a person, so do be mindful, an intelligent enough one might not be so easy to 'just get rid of' and it might even be ethically dubious to try. That said, like anon said

>As long as you have your basic memories in order (I.e you dont have dissociative amnesia) it looks like you have everything in place.
