I love doing impersonations of people.
First I was a mimic. Practically from the moment I began talking, I did impersonations of the people in my neighborhood - the storekeepers, the policemen, my teachers.
All I can tell you with certainty is that I, for one, have no self, and that I am unwilling or unable to perpetrate upon myself the joke of a self. What I have instead is a variety of impersonations I can do, and not only of myself - a troupe of players that I have internalised, a permanent company of actors that I can call upon when a self is required. I am a theater and nothing more than a theater.
There are people who do De Niro and Walken impersonations.
I don't have weird talents I'm just a weird person! And do impersonations.
I'm not very good at impersonations.
