Autistic personality - a mix of everything?

Do you often feel like \ would you describe your whole personality (behaviour, reactions, life views, convictions, interests) as a mix of every single person you ever met (even if you didn't necessarily liked them)?? It's like at some point you (sometimes unwillingly) have adopted something from another person and are doing this even 20 years later?

Best example in my case: As soon as I see someone doing exercise in the gym that I like, I start doing it too BUT if you show me it online I'll just skip. Only real life interest.

Second: The way I touch my face, walk, or even stand somehow emulates movements I saw by other people.

AND \ OR: every somehow significant interest you had like video game, fictional character, music, films etc all of them shaped you into person you currently are and you just "switch" between whatever thing inspires you in the moment. For example:

I often imagine myself being a specific video game character to dissociate \ deal with some specific task which for "normal me" might be somehow difficult

Or... when I listen to the music, I am choosing the mood, not the music \ lyrics themselves. Like the music should create specific ambience.
