I talk and walk when I'm asleep. My sister saw it several times, she sleeps with me, and she tells me sometimes I talk to her normally, as I was awake, but I'm sleeping. I know it's true because sometimes I wake up with different clothes, or in the kitchen... my mother goes mad. I also have some epileptic problems.
And I only fall asleep hugged in my teddy bear, that I have since I'm 2, and I'm 17 now ><
