I have all three of these experiences/abilities as well. And similarly, I think that as I get older my wake up timing is not functioning so well as it did. Possibly because my life changed so that I didn't really need it for many years. But now when I try, I tend to wake up two or three times, the first well before my intended target. And the later sleep is notably shallower and less restful.
