Tired

My dream last name made me really tired this morning.  I dreamt that I was riding in a vehicle of some kind.  I am not sure what kind, because sometimes we were on water, sometimes we were in the air, and other times we were on land.  It was always bouncing around a lot and I was hanging on for dear life with one hand while trying to write something with the other.  I have no idea what I was trying to write, I could never see the paper.  When I woke up this morning, all of my muscles were tensed up and I was really tired.  It really makes me curious as to where I was going and what I was trying to write.
