Mom is doing this very frequently, it frightens her. Mom frequently wakes up I guess after dreaming that someone is in her bed. One morning she dreamed someone got up out of her bed and she actually got up and started making her bed and told me she saw a gun (or a knife) in the bed under covers. Then she thought she should leave because she was at someone else's apartment and when she came into the living room she realized that she was at home. Is this normal for someone with Alzheimer's? Mom has this pretty much every morning. Is there any medication to help this?
