She believes that one of her ex-caregivers is sabotaging her by doing things that are totally absurd. For instance, Mom believes that this person sneaks into her house at night and plays music, puts sleeping pills in her coffee pot, moves furniture, etc. We finally had to release this caregiver even though we know none of this is true. However, that hasn't stopped Mom's delusions. And she says to us that she knows we think she's crazy but she knows what's happening. We are at a complete loss as to what to do.
