Thais is, my friend, what is happening to your conscious mind when it is awake during the transition from wakeness to sleep. While your body is fallig asleep, if you are aware WELL AWARE as me, you will hear strong buzzing sound, my leg ws up and I wanted to put i down but I couldn't. And I open my eyes amd oh My God the horror: black person infront of my head coming closee to me, and when it revealed its face it was bloddy red in blood, laughing at me...I was literally scared For life I'm gonna die, and then I closed ans reopened my eyes, the buzzing was even louder and stronger but this time there was a some kind of animal head and it put its head onto my face ans then when I started to scream, I could have felt the weight of it! I scream and yell, but can't yell cuz I'm getting paralyzed... When my body registered signs of me being awake, it instantly stopped that all and now I'm im bed in dark, NOT wanting to fall asleep again.....
Do not try to experience that...
