What does my 85 yr old mother think about? She stays in bed 95% of the time. Not interested in anything. Her quality of life is zero. Any advice?

My mom is the same -she is in assisted living which I thought could help her engage with people but she sleeps on the couches -it's very sad to have lost quality of life. My moms hearing is basically gone -but she didn't want to interact w people before that. My mom has dementia and its very sad to visit her -I live five hours away and when I visit I just feel guilt and awful that she is just existing now

My Mom does alot of that . ( but shes 96) I think it began when she started having significant hearing loss. At least that's my theory. She goes into what i call " Mom Land" mentally. Id check out her hearing and vision ..if you havent already. My Mom missing feeling useful too . So we bring the laundry to her to help fold and have her do small things , as much as possible. She like music , alot .. You might try that . Though with her hearing loss ..(even with hearing aids ) its hit or miss. I bought all these older songs l thought shed like . cole porter etc. Turns out she liked my Santana lol . Who knew
