I agree with all of the above. I'm very impressionable and try to avoid movies and shows about disorders...especially dissociation or DID so as to not adopt "their ways". I come on here and describe my experiences and what I go through and ask for some feedback about commonality.
We also can have an alter emerge that mimicks a person or character called what I don't remember.
I can hear the angst in your "voice"...so please describe your experience. My dissociation in switches are in various ways leading from to long and drawn out to instataneous switching between alters.
Do you have a therapist? Maybe describe to them what you experience for some feedback. I hope you read all of this and good luck.
