Jennifer Aniston was terrified when she found herself outside her house after sleepwalking. The former FRIENDS star frequently strolls off in her sleep and often doesn't remember her actions. She says, "I actually have done that. I have sleepwalked. "There is one time I can actually remember. I go to the same door in my house every time and the house alarm got set off. "That woke me up and scared the crap out of me!"
