In addition to Stephen McAdams reply about wake-up levels, doesn't this question also relate to phases in sleep cycles? Further anecdotal remark - recently I had a week when for several days in a row I was waking at either 3am or 4am but going back to sleep until morning within an hour or so. After a few days I noticed it always seemed to be at exactly one hour or the other and after looking for possible reasons in my appartment, eventually realised that I had accidentally set my watch so that it bleeped once, on the hour - it is so quiet, that although I had been wearing it all day each day, I hadn't noticed it while I was doing other things but despite it being some distance away at night it was apparently sufficient to wake me, but only at around that time.
