I do things like that, and I don't have dysfunctional brainy bits (as far as I know). :p I put cereal in the fridge, walk into doors, try to open cans with spoons, etc.
The worst ones happen when I'm tired. I was convinced that the fire alarm going off was somehow connected to my watch (it wasn't) so that if I kept my arm very still it wouldn't go off again (it did). Then another night I was so concinved that there was a diplomatic embassy from the owl kingdom in the bathroom. And I once got really confused about my rat and put him in the wrong cage, then got up and took him back to the sofa where we were sleeping. Poor boy, he was so confused. :p
Thank you for sharing your brain blips! I lol'd.
