Could this be sleep paralysis?

I have been dealing with weird sleeping issues. It doesn't happen frequently, it's happening tonight and yesterday after over 6 months without it happening.
It's always when I'm falling asleep, or if I've been abrubtly awaken out of a sleep. I'll always be super tired, and I would either start hearing things that aren't there and I start to feel really out of touch (the sounds usually go away a bit after unless I'm overly paranoid about it). My legs will feel numb, harder to control leg movements. Yesterday I had felt dizzy, and whenever I go to lay down and close my eyes, my chest tightens and I start focusing (not that I want to) on heart palpitations, and they get really fast. I've seen things before, but not as of recently. It just feels like it's impossible to gain control of my body when I feel like this, it's such an out of body experience. I can get back and neck pain as well, and I just feel extremely weird and unsettled. I also found drinking water during this was just so weird. It was like my brain couldn't process or understand how to drink water (I did it though). As of right now, I am exhausted and want to go to sleep. I had attempted to laid down, I had chest pain that's present on the left side mostly and feels like it's just there. & I also feel completely weird, my eyes get all wonky because it ends up being a bit hard to stay awake and focus thoroughly. I had also experienced (when this first started happening) it felt like my eye had rolled back? I also say when I move, it almost feels like I'm either moving too slow or like wayyy too fast for how slow I feel my brain is going. and like I don't know what's going on. It's really hard to explain, it's hard to be descriptive about something that's so... strange. I haven't had a sleep test done yet, I'm set to get a brain & spine MRI scan + a sleep test soon, maybe I could find answers there? Does anyone have any experience like this, any ideas on what this could be?
