I've heard this question from a few different people when reading up on dream forums and such.

It's always hard to tell whether you are actually "seeing the future" or if your subconcious mind can infer with great detail into the future. I'd like to think that regardless of the physics behind it, that the future is not set or predetermined. If so, then the most you could see is a possible future, which is just an inference anyhow.

But anyways, that's my 2 cents. I think with the loads of information that your brain takes in every day, it wouldn't be undeniable to think that our subconcious is often thinking ahead (no pun intended).
