My eyes are still bloodshot.

When I went to bed last night I thought I'd quickly fall asleep since I was so tired, but instead I had to lie there for a half hour or more as images of trees, road signs, houses, and endless highway appeared in my vision. There's no way to turn it off. It makes me wonder if my brain was replaying this stuff the entire eight hours before I went to bed. Thankfully I have no memory of dreaming about an endless road trip.
