Speaking of: Short-Term Memory Loss in the Shower

It's a bit freaky how often I get in the shower, spend 10 minutes contemplating the trails and tribulations of mankind, and then completely forget whether or not I have already shampooed or washed. I genuinely have no clue. I often have to check my loofah to see if it's wet.

I don't think I've ever sleepwalked, but this is definitely close. Being conscious for ten minutes of your life and not being able to recall virtually anything that happened during it? Sounds like sleepwalking to me.
