I don't believe dreams have any connection with the future. If they did, why would lucid dreams exist? Would you be changing the future through them? I highly doubt.

Infact I had a lot of dreams that infact were replayed in real life!My dreams are so vivid I feel them still when I half awake in the morning I remember many dreams that have happened in real life.When it happends to me I say "Hey!, this is pretty similar to my dream " Infact it is the exect thing that happened im my dream.

In the end I'll say this : Some people have dreams and then do the same things when they are consious, some don't dream and some can't remember what they've dream't until it happens.Dreams I think give us a hint, rather to what will happen in the future.

P.S. Sorry for some words being misspelt, my spell checker isn't functioning properly.
