If you think about it, ever since animals started dreaming I see no real "use" of it. I don't think it was ever essensial for life in any way, probably just an accident as far as evolution is concerned. This means that the subconscious mind was allowed to develop freely on some random path while the consciousness was always being sharpened by logic of reality and evolution. This is why in dreams the crazy things that happen seem to make so much sense and so on.

Seeing as the subconscious developed without the need for sharpening, why should we interpet dreams? If my theory were true then dreams could just be random... even a reoccuring dream may just be a random thing that the subconscious touches on and panics about. After all although we think it's important dreams were never important for survival (you never know they could have been but the possibilty is slim), so it probably never evolved any logical sense of it's own. Obviously I look at it from a scientific perspective and there is plenty science can't explain, so, any thoughts?
