He has vascular dementia and has declined severely in the last few weeks. Now he is talking about his hallucinations while in bed with me at night. He asks me questions about what he is seeing and hearing, and if I don't respond, he calls my name louder until I do. He asks me to do things like turn off a light, or a TV, neither of which is on in the room. This went on last night for 2 hours from 1:30 to 3:30 in the middle of the night! Before 1:30, he was talking intermittenly, so that I got about 30-45 minutes of sleep before the next question or comment. I have tried to ask him to not talk anymore and save his questions for morning, but it does no good. Anyone else experience this? I have to get some sleep! This has happened about 3-4 times.
