Has anyone had sleep paralysis before? I experienced my first instance of sleep paralysis last night and it's extremely odd. My eyes were completely open and I heard the voice of my brother, and the noise of my other brother running downstairs, this was all accompanied by zippers opening and closing. This isn't strange in any way because my parents are coming home from vacation and we usually greet them as they usually arrive late. I was certain that all of this wasn't real because my parents don't arrive for another 3 days so I tried moving my body and closing my eyes but was unable to. I became very frightened and began thinking about clenching and un-clenching my hand, I failed the first time but then my fingers began to move. This was all very dramatic in the moment and it just shows one how the brain can make the mind perceive what it wishes. The division between the two isn't well-defined but this experience truly let me contemplate the complexity of this organ.
