I went to bed last night at 11:30, and I woke up this morning at 2:00 AM. I just KNOW that I had been dreaming, which is really weird, because that's way to early for me to be dreaming. The REM part of my sleep-cycle takes four hours at least to really get working, yet I had been dreaming. Conclusion: I had a dream in layer 1, 2, or 3 of my sleep cycle. An odd occurrence, indeed.
