I have sleep paralysis that sometimes doesn’t allow me to breathe. Like I try to breath but it’s like not working. But 100% of the time I wake up before I choke. Recently I had one where I was a second away from choking but right at that point my body came back to normal. Shit was scary. Just imagine it as swimming but then your body stops and you cant move it. So you end up sinking in the water. You can hold your breath but you can only hold it for so long before you choke. So you have to pray that your body goes back to normal so you can swim back up, before your breath gives out. Your also realizing this is happening so it’s even more intense.
