For about a week now my Grandma has been complaining about nightmares. She wakes up crying saying they seem "ghostly". People from her past trying to make her do things she doesn't want to do, leaving her cryptic messages in things like the kitchen calendar or newspapers in her bed. Finding herself in dark abandoned places, and just things like that. Is this normal? I know she isn't going to be here much longer. She's already in hospice, but this is completely new. She never gets nightmares. I'm wondering if it's because they took her off donepezil, but I believe they started before. I'm not quite sure, but it was around the same time.
