I was 19 and in college , middle of the night I felt a high pressure on my chest, fully conscious , but I couldn't move , dread overtook me, something was there, it was really there it sucked my energy body out of me, I looked for a scientific explanation, all I got was a bunch of bullshit, there are energy feeding entities out there.
Scientifically they call it sleep paralysis, seeing ghostly figures, being unable to move , loss of muscle coordination, oh well thanks for defining it science ,soo very helpful.
