This happened in the early morning hours. It was around 3 or 4 in the morning. I wasnt asleep since i had already slept in the afternoon(?) the previous day. I fell asleep at 6:30 or 7 and i woke up at 11 at night. But i tried falling asleep at 3 or 4 in the morning and something really unsettling happened. As i was trying to fall asleep, i noticed that i wasnt able to move. I thought "Ok, sleep paralysis, happened before, whatever." i had slightly moved my lower back and my senses came back and i could move. Then i tried to fall asleep again and the same thing happened but it was a lot scarier this time. I was asleep, or i thought i was. I tried to open my eyes but they wouldnt open. I didnt feel anxious or scared, but confused. This is when it got scary. Slowy, my breathing was becoming constricted. Little by little, within a time span of 3 seconds, it was becoming increasingly difficult to breath. At the same time, i remember having a quick dream. All i saw in this dream was me in school and 2 girls in front of me, looking at me while covering their mouths with their hands. That was it. I had to forcefully breath and then it went back to normal. But many seconds later it happened again. This time i dont remember if my eyes were half or fully closed, but this time, it was like i had tunnel vision and in the end of that "tunnel" i saw a small gray dot. Again, my breathing was increasingly getting constricted. I forced my self to breath again and it had the same result, my senses came back. My room was dark since i have black curtains fully covering the windows, so no light couldve come through. After this, i just slept in a different position (on my side and not on my stomach with my head basically on the wall when this happened) and i slept and woke up just fine. Anyone else had this experience or can help me with this?
