Chance is you are not breathing in your sleep. You have Apnea or UARS and are slowly suffocating. Easy tells: you look like shit in the morning and it takes hours for you to normalize, you sometimes wake up all sweaty, you tend to open window ASAP in the morning "to get rid of the stuffy air", you are confused and/or have headache in the morning.
If you want to make sure, get a sleep study done.
Why do you think you are avoiding the bed as if you were afraid of dying in there. Exactly! You literally are.
I thought I had UARS too, and did a sleep study. I couldn't sleep at all when I was there. My neurologist then just gave me fucking prozac.
It's not that simple to figure out what's going on unfortunately.
