How the body knows what to avoid doing while sleeping

1.17K views

So this one came to me after a miserable weekend after surgery, I had a foley catheter in (its a catheter that is anchored in the bladder with a water balloon and is connected to a pee drainage bag), and in order to sleep I had to connect a big overnight pee bag and put it next to my bed. Now, I’m an active sleeper, I roll around and change positions a ton, so I was terrified of rolling over in my sleep and potentially yanking the catheter out, which would have been extremely painful at \*best\* and probably damaged my insides at worst.

Weirdly though, I slept still as stone, I barely moved for the 3 nights I had it in and I had no issues whatsoever. I’ve also noticed I do this if I fall asleep with my glasses or phone right next to me, I subconsciously avoid rolling over them in my sleep somehow and don’t move around as much.

How does that work? How does an unconscious body “understand” a danger/risk and avoid it?

Those who did the things that should not be done aren’t our ancestors. Apes sleep in nests on the top of trees.

Your are getting paralyzed while sleeping and your senses are ignoring the outside world. This way your acting in dream will not be connected to reality, not acting nor sensations.

I am SO GLAD I didn’t consider this possibility when my injury this year was fresh & I was in hospital with a catheter because I would NOT have gotten any sleep for worrying about rolling over and making it come out!

I DID have this issue last year when there were renovations and I had to move into a smaller room on a top bunk temporarily. I don’t think I slept for 2-3 days cos I lay awake worrying I was gonna fall out of that top bunk, crashing into the floor and hurt myself!

By day 3 I was so tired I finally fell asleep.
