Last night I went to bed before DH and when he came up I sat up and screamed, like there was a stranger in the room, then went back to sleep. I didn't remember anything about it until he brought it up this morning.
DS used to be a regular sleep walker. I've found him weeing in the kitchen bin, getting dressed, putting on shoes and running around the house, all while fast asleep. He has no memories of any of it.
