He wakes up at two am and tryes to get dressed then turns on all the lights,which wakes me and my husband up since we sleep in the next room with the doors open. I try to explain that if the sun is not shining in his window go back to sleep. The other day sitting in front of a bay window with the sunn shining in at noon, he woke from a nap and looked at the clock and said" boy it's late I guess I'll be heading to bed now." I explained the sun was shinning in so it must be 12 noon. He just say's OH! any suggestions?
