I got such dreams and OBEs... disadvantage is, I didn't know, and I will not know that I saw future till it will really happen. I have a few visions that may happen in future, and a few that I thought could happen, but didn't happen. I think I sometimes see possible futures, and maybe parallel universes.

Question is, is it possible to reach such level of prediction that I could change predicted future? Or- did I change something and therefore some visions of future didn't come true? I don't see turning points, therefore it is hard to steer line of events.
