Jim Carrey explains

“As an actor you play characters, and then, if you go deep enough into those characters you realize that your own character is pretty thin to begin with.

And then you suddenly have this separation and go: “Well who is Jim Carrey?”

“Oh he doesn’t exist actually.”

There’s just a relative manifestation of consciousness “appearing” and then someone gave him a bunch of ideas. They gave him a name, a religion, and a nationality.

And he clustered those together into something that is supposed to be a personality.” – Jim Carrey
