Trying to convince her this is paranoia related to dementia and he would not try to drive her out of the house. She recently moved in downstairs and she is convinced since that was her grandson's space prior that he resents her taking the area of the house and saying he is purposely causing loud startling noises in her room and stealing her things and turning down her heat. None of this is happening and we will offer to show her proof even but to no avail. Tearing me up that she is not happy here now and that my son is targeted. Not feasable to block all noise with pets as well running around! Looked into sound proofing floor and ceiling in her bedroom at least, but trying to pay and install - just one more thing on the list of what I need to do and already maxed out. Someone suggested ear plugs but I doubt she will do that.
