Hey, hope things get better for you as far as the drinking is concerned.
And yeah, interesting that you post about this because I have had the same kinda of feelings too when I was in the window space b/t having drank alot and sobering/detoxing in the past. The first time I experience something somewhat like that was about 5 years ago (when my drinking sincerely got out of control )
I'd think I'd be seeing things and when I did fall asleep I would jolt my body (like my leg or arm) and it'd wake me up but it felt like I was pulled or something)
-Come to find out that happens to people just in the midst of sleeping (since I'm kind of a light sleeper it'll wake me up). Some people don't.
Not gonna get into too much but yes, I know its a really eerie and worrisome feeling, trust me. That paranoid feeling is a headache and emotionally draining.
As you sober up it subsides (if its the alcohol and/or detoxing phase that caused it)
I take Melatonin to help me sleep (don't take it everyday). Worth a shot if you're having trouble sleeping.
Prayers to you
