No - your dreams are about everyday places and people, in general, so sometimes your future will look like your dream. Deja Vu is a sensation mostly - they have seen the brain activity and it is not recollection activity when the scene is "seen again", it is creation activity of a different sort. So you are just seeing the scene in a special way, not remembering a previous view of it.
Your dreams are a view of what your subconscious is thinking about - mostly fears and lust, sometimes people it misses. So it sends this information to you in strange and often gruesome dramas using ideas from your own memories as symbols of what it wants to discuss with you. The subconscious is a primitive area, so the visions can be vivid and disturbing, but they usually deal with pretty basic stuff, once you cut through the symbolism.
