How Evil Spirits Use Sleep Paralysis to Create Fear

I was sleeping the other night when I found myself sitting up, trembling with fear. This was not a natural kind of fear but a supernatural one where I was paralyzed. I looked across my room and felt a very evil presence but saw nothing. It was like a fog of terror was throughout the room and even though it was around 5 in the morning, somehow, the room grew even darker. Have you ever seen the Twilight Zone? In that show, the lighting of a scene will change dramatically as the characters experience some kind of twist in their supernatural/unexplainable adventure. That was the kind of effect that was going in my room, a sudden darkness and a haze. This clip here more or less shows the hazy quality of what was happening.
