[|Human|] My wife is bedridden, on 3 liters oxygen full time, has controlled diabeties (metformin), history of crohns and COPD, hypertension. She has become very confused, has nightmares, and sees people and things not there. also can not stay awake. she is 62 years old, and grossly obeese
[|AI|]  Areas you are suffering from multiple medical conditions, Some medications disturb REM pattern of sleep, which CN cause nightmares. Even underlying depression or anxiety can cause nightmares. Being bedridden your sleep wake rhythm may most probably be disturbed. it's my advice to he proper sleep wake schedule with relaxation exercises like meditation, which can be practiced despite being bedridden. But if still nightmares are distressing for u, u CN be put on some medications to regularize your sleep wake rhythm after proper assessmentRegards
