Question about religion and reincarnation?

I've figured out what religion I am: Humanist, which is sort of like atheism, but the theory for humanism relates more to science. so basically, I believe there is no god. BUT, part of humanism is that reincarnation isn't real either. I'm not sure what to think about that. Sometimes I think it's not real, and that it's just wishful thinking, but on the other hand.. I have these dreams about being on the Titanic, and all these other things about me that are like the characteristics of someone from that time period. maybe I was reincarnated, and I was someone on the ship. I really don't know what to think. Anyone got any good.. uh.. theories?
