Hey guys, I was wondering what you think about this. My Grandma lives right behind me in her own house. She's 86 years old. We've offered many times to let her stay at our house, but she's very independent, and refused. Anyway, she's been telling me that she hears somebody knocking at her door at 2:30 - 4:00 AM. She also has told me she sees flashlights shine in her window, and her phone rings once or twice at night. She's even told me that she's heard voices outside of her house. I visited her today, and she said she heard the knocking last night. I looked all around her house, and there's no footprints in the snow, besides mine of course. I have absolutely no idea why somebody would do this. We live down a dirt road, and I can hear if any cars come down. I was awake most of the night, no cars came down my road. She told me this has been going on for about a year. My parents are pretty much ignoring it, saying It's her imagination. I'm extremely worried about it, because my neighbor had his house robbed last year, and they never caught them. I told her to call my house when this happens, but she keeps saying "No, I don't want to bother you". If I lived alone and heard these things, I would shit bricks. My Grandma isn't afraid of anything.
Do you guys think It's her imagination? Is there anything I could possibly do about this?
