It was like a hiccup inside my mouth, i never breathed through my nose so don't know if it was really unable to breathe but not through my mouth, like i open it and it was trying to hiccup but nothing comes out, and didn't let me breathe through my mouth. Lasted about 4 seconds, i'm laying on my pillow and it feels as if my throat is gone and unable to breathe with my mouth open, just a hiccup thing with no sound or anything coming out, my neck felt like it had no adams apple, later on i felt my neck and it was all soft like. like when you sleep on your hand and cant feel it but it's all super soft. it was like that but with my neck.
