I talk to myself, a lot. I only do it when I think I'm alone. I tend to suddenly start laughing, if people ask me what's funny I can't remember it. I haven't managed to do that during a sad moment, thankfully. I often find myself staring out into the air, not thinking. It's quite relaxing.
I used to sleepwalk too. Wandering around the house, looking awake but you could see in my eyes I was asleep. When I was about 4-5 years, I could suddenly sit up and start screaming. I robbed my parents of a lot of sleep.
