Some people say dreams have meanings, they aren’t there for nothing and they correspond to and event in our lives that happened or is going to happen.  For others it’s a form of precognition as with the bible story of Joseph the Dreamer. Sometimes we dream of people that are already dead and events that we do not understand.  If we are just dreaming things that we just think about then why are we dreaming about random things that never crossed our conscious mind. Does astral projection have something to do with it? Are we traveling or the souls of the ones who are dead entering our dreams?
