I was in one for a week. I had sleep-deprivation hallucinations, and I researched my brother's schizophrenia, so I knew generally what to do to recover. Which was be healthy, and I asked for a solo room because I wouldn't be able to sleep if it wasn't, which was true but it felt like a lie. I was totally paranoid. First day I danced during breakfast, and someone had a hoody with clock gears and stuff on it so I was reminded of a cuckoo clock. So my brain harped on that for a little bit.
Why I had sleep deprivation in the first place was because granny had cancer, mom had diabetes, older bro was abusing drugs and had a small episode, and another bro was being schizo and screaming for 5 hours about veganism and paranoid delusions. They went to the hospital a dozen times, and it took aeons for their meds to get sorted out. He is fine now, but later admitted be considered murdering us, so, eh. Because he is schizo and I was close to him though and his brain quality was deteriorating he frequently had hallucinations involving me abusing him, and thought random people outside all shared my face.
All that stress and him randomly barging in my room with paranoia, I just couldn't get sleep in, and tried hiding away in my room on the internet, but I also had college to deal with, and I got into veganism because his persistence paid off, and it wasn't enough calories, then I just had the breakdown at college, then hallucinated in my sleep, two sets of vivid 'dreams' at once due to a failing corpus calossum. Time seemed to go by fast. My eyes couldn't focus, I looked at people indirectly, my eyes were being lazy and I saw someone and my eyes were looking at an angle to make it look like the person I spoke to only had one eye instead of two. I was hanging out in some toxic 'spiritual' chatrooms as well which added to the sleep loss and stress.
It was hellish, and people saying they are crazy when they really mean weird annoy me because they act like its cool, and its just about the worst thing that can happen to you.
And I lost my faith during a college history class was when I was finally pushed over the edge of sanity. Months of getting 4 hours of sleep a night and laying in bed most of the days finally took its toll.
I was afraid of going to the hospital so when they asked me if I was a danger to anyone I said yes! Because I wanted to appear tough to avoid getting attacked. That only got me a police escort with a hospital transferal lol. I was in a straight jacket.
Thats all Imma say, other than the hospital had to legally give us gym time and neglected to do so, I ended up doing squats in my room for exercise, which is an important part for mental health, which I recalled from what I googled for my brother. That, sunlight, proper diet and social environment and sleep etc.
