Waking Up Over and Over

Had some trouble sleeping this morning. You know that thing where you wake up and think you're awake, but it's just a dream? I did that about five or six times this morning. Several times I awoke to another dream in which I missed my alarm and was late. Worst dreams ever.  I've never done this before, and it was making me sick.  (I think it all happened in the span of less than two hours, though because I was dreaming, it's hard to know.)
