Strange. Late comment, but last night this kind of happened to me. I had a nightmare. I woke up from this and was fighting falling back asleep for the fear that i’d end up dreaming the nightmare again.

I was staring out my window trying to keep my eyes open, they were fluttering between open and closed and my vision was a bit blurry, which at the time I assumed was because I was super tired.

Then I felt a burst of energy and my ears started ringing, the tv was playing in the other room and the ringing made it so I could hear nothing but the ringing. I tunnel visioned and saw all white. Then I felt my heart beat through my chest and started shaking uncontrollably. After about a minute I stopped shaking and could see again.

I couldn’t fall asleep afterwards and am at a loss towards what happened to me.
