Grumpy

I'm grumpy.  I'm not really sure why... except that for the past few nights I've had awful nightmares that have kept me awake for half the night.  The worst part is that I can't remember what happens in the dreams so that in wake I might be able to make some sense of them.  I mean, I remember a tidbit here and there, but nothing substantial. 

For example, last night I woke up at least three times after having turbulent dreams each time I started to doze.  All I remember is the color green, the face of a college friend (Carla B.) and being in Vail, Colorado.  The night before I just woke up angry, and the night before that I woke up terrified.

What gives?!  Any suggestions to shake the bad dreams?  I'm all ears.
