About an hour ago, I was trying to fall asleep and I also had calm binaural beats in the background. I was flat on my back and I was totally still just looking into the blackness while closing my eyes. I couldnt see any clear hypnagogic patterns but there was like boxes growing bigger and it kept repeating a square growing until i ccouldnt see anything but then i saw a quick flash of light!? I didnt feel any vibrations or noises or anything like that.
My brother then knocked so loud on the door that i had to get up but... I tried and it was really hard and i kept shaking, also, i got up starting with my head then my arms then stomach then legs then feet because it was so hard to get up and when i eventually did, I was shaking all over!
I opened the door for my brother but I wanted to make sure I wasnt in a dream so I did a few reality checks but they didnt work and neither did flying so i was sure i wasnt dreaming. Did I enter sleep paralysis?
