I had a dream in which I woke up, went down to the kitchen and started talking to my mom. That sequence turned out to be a dream-within-a dream, so (still in the dream) I woke up, went down and started talking to my mom. This chain of events went on for about six iterations until I really did wake up. I turned on my lamp and just lay in bed literally pinching myself to determine if I was finally in reality. I was more freaked out by it than by any monster in the closet nightmare I have ever had.
Crazy dreams are at least entertaining.
I hope your headache gets better.
