Did you ever have a dream where you tried your hardest to wake up or move, but you couldn't? This happens to me sometimes. The room looks exactly as it did when I fell asleep and I try to speak, but I can't. It was one of the scariest things to ever happen to me.
I consulted the great, all-knowing Wikipedia, and I found that this phenomenon is called Sleep Paralysis. During this, your mind becomes aware, but your body still thinks that its asleep. Sometimes people will even see stange creatures or objects In fact, some scientists believe that sleep paralysis can explain some paranormal things. Some people who claim to see ghosts were actually experiencing sleep paralysis at the time.
What do you guys think? Have you ever experienced this before?

I've had something similar to it once, but I also felt that something heavy was on my chest and I couldn't breath either. It was scary.
I have other nightmares as well. Hate them.
