Dad just turned 86. He seems alert and quite "normal" until he starts to fall asleep. Then he'll wake and just talk nonsense. He swears there are people in the room, and he will often seem to be folding laundry or something to that effect when he is sleeping. He has also sworn that someone is stealing his wallet in the middle of the night. I really don't know what to do. I'm not sure what the options are, he has no health insurance (my parents are legal immigrants and have been living here for about 15 years). I really need some advice.
