This needs to become a thing . <| sep |> If she ' s barely able to hear someone shouting at her but she claims that she ' s being woken up repeatedly by tapping on her windows , you ' re probably right it ' s probably auditory hallucinations . We deal with this sort of thing a lot . It ' s not unheard of for people to mess with older folks , but if the police are that familiar with her from coming to her house that often and finding nothing out of place , it ' s much more likely that she ' s hearing things . Where I work , we ' re required to respond to calls like that no matter what , and a certain point it becomes a waste of our time and resources to continuously respond to the same call where we ' ve found repeatedly that nothing is going on . We ' re definitely sympathetic , and we ' re not going to go arrest an elderly woman who is calling us for help because she thinks someone is tapping on her windows . But we will try to contact a family member to let them know about the situation so that they can try to get them some help . Maybe you could spend a few nights with her and see if you can hear anything going on outside . Maybe there ' s something inside the house that ' s making a tapping sound that she thinks is coming from outside . If not , you may want to think about taking her to see a doctor to figure out why this is happening .
