All I know is that last night, I was having so much trouble sleeping with only a couple hours of sleep. At one point, I actually felt a body-numbing from the waist up. But I could feel myself moving and trying to utter my brother's name despite not even being in the room. I felt like something was going terribly wrong at that point.

Then, it ended and what surprised most about this is that in the real world, I didn't move a single muscle. I was horrified by what just happened and that I was still the whole time. 

Was it because I was sleep deprived and had a hallucination? Did I have a seizure? Was I dreaming? Was I accidentally astral projecting? I need answers!
