I have been my mom's caregiver for the past 2 years. She has been diagnosed with onset dementia. Recently, within the past couple of weeks, she is having full blown conversations with someone. She is not talking in her sleep because that comes out like gibberish. She is actually having a conversation. When I enter the room and ask her who she is talking to, she snaps back and looks at me with a blank stare and says "no one". I wonder if she's talking to family members that have gone before her. I wonder if her time is near. She is nearly blind, cannot walk, and has trouble communicating. She sleeps about 18-20 hours a day. Kind of creepy when I catch her in conversation with "someone".
