badassbob is right. I have had this thing where the alarm goes off during non-REM sleep, and then I wake up after a short dream, but the reason is that the alarm just won't wake me up during non-REM, and it was going for a good 20 minutes before I naturally entered REM and woke up. It is just a phenomenon of you not waking up until you enter REM most likely.
