Weird very realistic dreams(Or something else) that seem to coincide with my girlfriends?

deja vu. not sure if you believe in reincarnation, but i certainly do! my interpretation is that you remember things in your past lives. and you can remember everything so clearly and you are getting confused trying to distinguish memories of you past lives and your current life, because it is almost time (probably a couple lifetimes away) for you to reach a place which, in my religion, we call nirvana. it's when your soul has reincarnated so many times, and it has been purified, so it is coming to the time where you move on into another place. but hey, this is just what i believe, i'm not some crazy cult.
