Any idea on what's going on? Neighbor is 87. She hears music that isn't there, is having an affair with a guy that's in her mind only, makes meals for him and when he doesn't show because he isn't real, she tosses the food out. She tells her neighbor to be careful what she says because the guy can hear her. Asks neighbor to listen to the beautiful music that isn't there and woke a neighbor at 2 in the morning looking for boyfriend that isn't real. Knowing all this, her family moved her to Indiana to be near family and she didn't handle the move well at all. Now she's in the hospital to see what is causing all this. She wasn't like this just a few months ago. She went from an active, intelligent adult to someone scary. She did have a UTI a few months ago but the hospital says she doesn't have one now. Any ideas on what's going on? I had her as a neighbor and am worried sick about her.
