Do you believe in reincarnation?

I've read a whole bunch of stories on people claiming they've had past lives, and I personally believe that if it is real that I'm not in my first life (I'm not crazy, I've had this feeling for as long as I can remember.) I'm just curious on what other people have to say on the topic. What do you think of it? And if you do believe in it, do you think you might be reincarnated?
