Yes. I used to settle my husband into his armchair, and sit beside him, putting my armchair in front of the door so he couldn't get out without waking me, every afternoon, and we'd both snooze for an hour or two! Often I'd wake up and find him watching me, smiling. He was fine, as long as he could see me. In the night, however, he'd be up, wandering around the house, because he wouldn't see me in the dark, and would go looking for me! A few times, he left the bedroom without waking me (he was only sleeping 1 1/2 to 2 hours at a time, so I was exhausted), and I would find him in the living room, in the dark because he didn't know how to turn on the lights, very frightened because he couldn't find me, and didn't know where I was. I had motion sensor lights everywhere, but in his fear, he would be sitting very still, so the lights would go out! During the day, I couldn't leave him at all, he had to accompany me everywhere. Even to the loo. If he couldn't see me, he'd panic. Because I was the one who "knew everything".
