*Somnambulist is the fancy word for Sleepwalker
I know I've sleepwalked in the past, but until last night I'm not aware of having done it for a long, long time.
So I wake up clearly half asleep and pretty much completely out of it, crouched down on the floor with both hands also on the floor. Now, I'm half asleep and wasn't really thinking clearly at all, but for some reason I basically jumped from my squating position on the floor on to my bed.
Once I was in my bed, I pulled the covers over me and tried to fall back asleep, but felt a crazy pain on the top of my right foot and the top of my left hand. For whatever reason, I disregarded the pain and tried to fall back asleep, which I ended up doing.
Woke up this morning to a painful foot and hand and looking down, found that there was a huge bruise on the top of my foot that's about 2 inches long and 1 inch wide in the shape of a rectangle.
