Choking in my sleep

This happened 2 times in one week, I was sleeping and I have this dream that I’m underwater and I can’t catch my breath for the life of me. I don’t have anything on my face when I’m sleeping, I do sleep with my headphones,but they don’t wrap around my neck. I try to wake up and it’s like I’m frozen. On top of that I deal with heartburn,but I have been noticing I have like acidic feeling in my throat that’s been killing me in my sleep and I feel like I want to vomit,but it just sits in my throat and I do choke. I wonder if that’s what happens in my sleep? If it is what do I do? I don’t like the feeling of choking in my sleep.
