Someone please tell me why I just woke up out of no where into a panic attack

Like I was panicking in my sleep and it woke me up?

I can't even breathe right now and I cannot calm myself down even though I know everything will be fine

I just want to go back to sleep but every time I close my eyes and try clear my mind of one thing something else popped up and my chest tightens and I get really hot and now there's ten things jumping around in my mind that I don't want to stress about at 6 in the morning

Uuuuggghhhhh I'm not supposed to be up for another two hours whyyyy ;;-;;
