sleep paralysis is scary is fuck it really gives you a true feeling of helplessness that you never think that you would feel especially if it is accompanied by hallucinations. I have experienced it twice and both nights had been the scariest moments of my life. After the second time it has happened to me i figured out that sleep on my back triggers it. The feeling is so real that you panic and i have woken up screaming from it and the first time it happened i woke my family up.
