Every night for a little over a month, Mom has been "seeing" the apparition of a woman holding a baby, sitting atop of her dresser. It always happens after she goes off to sleep. The night before last, I heard her say, "Close that drawer!" I got up, and she was standing outside her room (which was dark), and she said she was sick and tired of people just coming in like they own the place. She asked me if I saw the person & I told her no one was there. She said, "yeah, they just disappeared again". She got up and sat in her chair and said she was going to wait until they came back so she could tell them that this was HER room. After about 10 minutes, she got up and went back to sleep. I was only alarmed because she was so serious about what she had seen. She goes back and forth talking about the vision like it was real and then in the same sentence knowing that it is not. She is 81 and does not have alzheimer's or dementia, and has never shown any signs of either. I'm just concerned if this could be a precursor to something more serious.
