Anyone ever have the feeling that you are sort of acting and observing yourself in your everyday life and conversations?

Usually I find that I am able to have conversations with people normally. But sometimes I will have the feeling sort of like if I am reading a script and acting out my responses to people. And there is a separate entity sort of watching me and the situation I am in as a detached observer. It is hard to explain. I picture this using the analogy of the movie "Scream" where there are two killers when it was only supposed to be one.
