Over the past year my mom has been having fairly vivid and detailed hallucinations (primarily auditory, occasionally visual). They began "simple" such as people speaking and singing at night (which wasn't really likely as she lives on a farm in a rural area with no close neighbours). Her hallucinations have evolved to become more complex and are now causing her stress and anxiety. She is currently focused on the many visits she has from her German relatives (her birth country) who are constantly harassing her. My evil drug addict cousin was operating a tour company from Germany to bring tourists to her house all summer (helicopters included). Also my aunt and uncle (her brother) continue to harass her about selling the house. She loves her cat dearly and is often worried someone will hurt it. In reality her family is very nice (not evil drug addicts) and no one has visited from Germany. I was there last week (she lives about 5 hours away). After a couple of days she told me that my fiancee (who was to arrive that day) and I wouldn't be able to sleep in the guestroom as that room belonged to her friend (who helps protect her from the evil relatives). When I was last visiting I overheard her having a conversation with my aunt - she was talking outloud and there were pauses in the conversation (so like she was "listening" to a reply).
Her symptoms are completely intermittent. Two days ago I had a 40 minute phone call with her where she was 100% normal. Then last night she called me because she heard my cousin in the house with a realtor! (I calmed her down - I stayed on the phone while she checked all the doors and put things (like a bag of cat food) in front of them so people couldn't get in).
A few other bits of information:
-she's not on any medication
-physically she's totally fine. The house is spotless, the large garden and yard is immaculate, she's active outside, is cooking healthy food, taking good care of the cat and herself. She's not a danger to herself or others. I'm not worried about her safety.
-she lives alone in a small rural town. My father passed away 3 years ago. I'm an only child and we have no other family in the country.
-she loves her house and is adamant that she doesn't want to move
-her memory is decent enough (other than occasionally misplacing things and then blaming "people" for moving/taking them!)
-she's pretty anti-social, but always has been.
-she's *very* anti-doctor, anti-medicine. She always has been.
-she doesn't have a family doctor and hasn't been to the doctor in probably 15-20 years. Her philosophy is she feels fine, so why would she need to go?
To her, everything that is happening is 100% real. I'm not sure what (if anything) I can/should be doing. I'm at a total loss! Any advice or suggestions would be appreciated.
