Sometimes the OH goes downstairs for a few hours, if he is having nightmares or can’t sleep. He did last night about 2am, so I wasn’t too bothered, but then I can’t sleep, and lie awake to listen. About 4am, I could hear what I thought was the inner conservatory door close, then 5 mins later odd noises. So I got up, and there he was outside the front door, in my dressing gown, with my glasses on, trying to get in using the shed keys. He had gotten out through the conservatory door, and went around the house. He couldn’t remember how, why or what. That’s a first. Does this happen to anyone else?
