Breathing, sleep hallucinations problem.

My mother 75 years diabetic, bedridden for 6 months is unable to to sleep at night gets hallucination of something touching or kept on her. Feels bones poke bed so cant sleep. Sleeps in daytime. On giving more salt in food, fruit juice coconut water became better. Is it related to salt or electrolytes imbalance. Sometimes she gets breathing problems and it goes away after 10-15 minutes earlier it was daily once during day once at night but since few days it is less maybe once every 2 days. Since 2 months she lost lot of weight muscle fat and unable to sit, walk. As diabetes since 2008 and knee problem 2017. Very fearful of change, depressed not opening eyes. But memory is powerful. I have written a report on the medical details and can send it to you buy attachment if you tell me how to.
