Dreams as a new symptom.

The brain can no longer differentiate between dreams, TV and reality.

I walked into my Moms room one day and she told me the Doctor wanted to talk to me. It was Dick Van Dyke on Diagnosis Murder. I did say "Mom thats the TV" and she said "oh yeah".

Some days my wife wakes up but stays in her dream. It's like there's no filter between a sleeping dreams and being awake. Even the shape of her face changes when she's in a delusional (waking dream) state. I can tell when the sundowning is about to start when she starts loosing control of her eyes. One eye will start wandering way off from the other. That signals that she's going into basically a dream state even though she's wide awake. When she wakes up like that, all I can do is sit with her, talk calmly and help her work through what ever she's dreaming. The goal is to get her calmed down enough to rest easy and fall back asleep.

That has to be terrifying for everyone involved. Are there any prescribed anxiolytics? Maybe it's time. There's good reason why benzodiazepines aren't first-line medications for sleep and anxiety anymore. Still, towards the end of life, I think they have a purpose to maintain a peaceful, quieter mind—just my opinion.

Take away the phone or have her taken to the hospital where you then do the unsafe discharge thing.

Me, I’d go for the phpne

I think that your mother's condition is deteriorating.
It is time to call her doctor to check in with next steps.
