Canada, Work and my body's unwillingness

So, I got to work today (that's where I am now, btw) and couldn't focus my eyes. the phrase "to tired to see straight" comes to mind.
I hadn't slept well last night, and I am pretty sure I had WoW dreams - I woke up certain that I was at an extreme angle, and was really confused and upset that I couldn't fill the bag with purple (no, I'm not certain what that means). Once I got to work, I found that my eyes would not stay converged. If you don't know what I mean, look at a Magic Eye picture. Notice how your eyes go wonky? My eyes wouldn't stop doing that. So I took a nap in my car after clocking out, and came back sweat-soaked but refreshed. I sat down and worked for about 20 minutes, and then my nose started bleeding, somewhat spontaneously.
30 minutes later (!), I came back from the bathroom, my nose finally not bleeding any more. I don't think my body wants to be at work today. My mind sure doesn't.

Tomorrow, I leave for Canada to play in (and run games for) Ancient Enemies? A Zeif / Duchy Bordercon... which is to say, I'm going to play D&D for 4 days straight. I should have fun.
