Something about my room I don't understand.

I think your body is right. There could be something harming you. Any chance for gas leak? Mold somewhere on the wall or something forgotten in a box (I once put moist walnuts into a glass dose and forgot about them and couldn't figure out why I felt like suffocating)
Something possibly triggering allergy?
Wrong mattress or pillow messing with your breathing?
Isn't there too warm in the room?

Clean out your room.
Re-arramge it.
Put a new energy vibe in there.
The power of the mind can do incredible things.
Look at your patterns before going to bed and differences in environment.
What do you do different in the lounge than what you do in the bedroom?
- it might be your orientation to the door
- it might be stimulus before bed (tv)
- it might be lighter or darker than your bedroom.
- is it the height of the bed, the mattress hardness?

+ burn incense
+ Get a night light (there are really cool ones
+ Get a white sound generator or sleep-buds to listen to ASMR.
+ Change your bedding type
+ Look up 'healthy sleep environments'.
+ Only you can observe and notice the differences and make the necessary changes conducive to your needs.

It could be bugs in your mattress, you might want to get one of those mattress protectors that zip closed, they will seal all the couties inside. They also make them for pillows.
Another one is having your cell phone near your bed. Hackers can gain access to it and hear when you go into a deep sleep, and then say things to you making you wake up. They may even be making monster noises. As soon as they hear you wake they stop so you don't know why you woke up and get into a bit of a panic.

I like Angel said try sleeping with light on, and I was going to add maybe put on some nature sounds/light music.

Heres what worked for me stay on the couch until you are sleepy until you can barely keep your eyes open and then go to your room as soon as your head hits the pillow you should fall asleepb but leave a light on even if its a closet light. I have a lamp on a timer. Your mind will be too tired to focus on any sleep paralysis. I am telling you from experience.

Can you go i there and redo the room? Maybe a difderent color or colors to brighten it up . Maybe change the light also.I hope things change for.you soon

Sleep paralysis is fun, right. I woke up couldn't move. My body was buzzing, I looked at a closed door and could see someone/something looking through the door at me.

Open the window, day and night. Ask the vibes to leave or leave you alone. Light it a candle to find its way out. Thank it and own your room.

Might want to get an EMF meter. Unshielded wiring or old TVs can do all that.
Or could be paranormal. Eliminate the obvious first.

Maybe your bed / pillow combo is impacting your ability to breath easily?

Try sleeping in there with the lights on

Spirits in there

I guess u could try a dream catcher just put it above your bed

Oh wow!! Spooky

Did you put anything new in your room? Something given to you? Thrifted?

Do you think it could be psychological or something really going on with that room

Say prayers. Smudge the appartmenr.
