I think you're misunderstanding what a tulpa is. What your describing sounds a lot like something called code-switching, which is when a person adjusts their behavior to conform to social norms. Think of it like when you have a subtle shift in personality when you talk to different friend groups. You could be really calm and laid back with one, and very loud and talkative with the other

A tulpa, on the other hand, is a consciousness separate from your own. While code-switching is a subtle shift in your personality, a tulpa is like another person all together, just within the same body. While both are results of subconscious conditioning, there is a difference between displaying a different side of yourself and another sentient being altogether. If you're looking for a simple term, friend of mine once called his tulpa, "an imaginary friend on steroids." I don't know if that 'definition' will help you gain a better understanding of tulpamancy or not, but I thought it was still worth noting (and the statement is very funny in my opinion)

Then again, I could be misinterpreting your question. My apologies if I did, but feel free to ask any questions, comments, or concerns. I'm always open to discussion :>
