I'm almost 100% positive I'm not the first to think of this. But what do you think about our real life experiences being dreams for the subconscious? Just as we cannot remember every dream (I'm sure even the best dream recall misses a few dreams) perhaps the subconscious cannot remember what we do during the day. And if this is so, then it begs the question, Does our subconscoius remember much more concerning our dreams than we do consciously? Just as we can recall a great deal in the waking life, perhaps the subconscious can recall a great deal in the dream world. This might also explain why we only sometimes dream of our day's events. Because the subconscious happens to remember that particular event. Just as we can only remember some dreams and not all.

Anyway, I had some extra time and thought I'd post something which was on my mind!
