Hi, my mum has dementia and for about a year is convinced that two family members she hasn't seen for years, are breaking in and wandering around the house all night. She has a new front porch door, a new lock on the inside door and two new bolts. However she still believes they are getting in. I suggested a security stick that you prop against the door although I know when that is in place she will still hear them. Can anyone offer any advice on what I can say to her? She is very agitated and I'm just not sure what to say anymore to make it better for her. Thank you
