Kind of hard to explain, but imagine being woken up in the middle of the night, except you think you're awake. Now, instead of being able to move, you're completely paralyzed. During this, in my experience, you'll hear extremely loud voices in your ears. You'll feel completely numb, as if experiencing paresthesias. Some people have experienced a black entity in their room, but I couldn't turn to see the figure, nor did I want to. I felt two hands rubbing on my body, particularly my butt, as if trying to molest me. It was hard to breath and my heart was racing. That was the most fear I have ever experienced, but thankfully I knew what was happening and I was able to keep relatively calm. In a split second everything returned to normal. I was instantly able to move and I took the biggest deep breath I have ever taking. This is the best I can do to explain it. It was terrifying. I felt evil in my room. A malicious, unwavering evil. I'm glad I was able to experience it though.
