Hello my name is Trisha and my sister has Alzheimer's. She was diagnosed a couple of years ago. Our mother also suffered with the disease. Lately she has been having terrible nightmares where she says she hears beeping noises and something coming up, up and up. She describes it as white but does not say its ghost like or anything just white and the beeps. She keeps saying after this happens more than three times she knows she is going to die. Has anyone else experienced an Alzheimer's or dementia patient making statements like this? Any info would be appreciated. Thank you
