Are dreams capable of revealing one's future?

Absolutely. They're called precognitive dreams, and there are many cases on record, most notably, Daved Booth, who dreamt of the crash of AA Flight 191, in Chicago in 1979, 3 days before. The FAA logged in his calls, but he couldn't give them enough information to go on.

Yes, they are. I've had quite a few minor Premonitions that ended up coming true. As for anything major, I can't remember having one to have come true yet unless, of course, my memory really is that bad and I did.

Happens to me alot, But its only small things like buying a candy bar and such.

Premonition.

No. You can base your actions on the dream to create it yourself but dreams are byproducts of unresolved emotions they don't predict the future

No, but they reveal your anxieties and desires.

I think so.
