Compared to other problems posted here it seems trivial but what happened was unnerving.
I was sitting on my bed last night when I felt a sensation of falling. It felt like the ground opened up and I fell...plummeted is more like it. I felt the jolt when I landed. Felt it in my head that is. No sensations of the rest of my body crashing...just my head. It was so real that I put out my hands to break my fall and then looked down to see where I'd landed. I was still sitting on the bed
