Mom is quite elderly and suffers from depression, anxiety, and dementia. I am a senior citizen myself and have moved into her house to look after her. Frankly, her room usually smells. I sleep on the floor in the living room and need to listen to podcasts or something to get to sleep but the light from my tablet bothers mom and so would the sound. I've slept in my own room since I was 2 weeks old and prefer being on my own. Suddenly, mom wants me to sleep in her room. All the practical issues could be dealt with. But I get squicked out by the idea of sleeping on her floor - it just feels creepy. I am literally right on the other side of her wall, and can hear her and go to her quickly when she calls out. This arrangement has worked for years. Am I wrong to be creeped out? Do I have to do it? I am sleep deprived as it is!
Mom sounds a little scared.
You need to figure out some comfortable, supportive sleeping arrangement for yourself. Sooner or later, sleeping on the floor is going to cause harm to your joints.
Also, if Mom’s paranoia is overwhelming (sounds like sundowning) maybe a call to her doctor for a meds adjustment?
