Yea... that's a crappy feeling. *hugs* When I dream I am so many different people, and they are strangers, some of them are lives I have never lived and don't understand... when I am awake, it's often the same.
But, I will say that as I get older this feeling became less strong. It was especially bad in my 20s. Now I enjoy it a little - trying to camouflage myself with them, even when I don't get it, and sometimes when I do that, I do get it. Stay strong
