Head Quake

Don't remember much, but sum of it was this:

I awoke (in my dream) to discover that the entire building was shaking and quivering like jelly. My ears were filled with a base growling, emanating from far below.

"Must be an earthquake!" I thought to myself, and I began to frantically run around, struggling to keep my balance, as I woke everyone to alert them.

"Keep calm! Just get under your beds, or under your tables" I shouted. But everyone just looked at me with puzzled incomprehension and no one seemed very concerned. This lack of response agitated me into a state of worried panic, "What's wrong with you people?" I screamed, "Protect your selves, for God's sake!!!"

Subsequently, they sat me down, calmed me and after much talking, it was patiently explained to me that "There is no earthquake...it's only in your head"

No one else was experiencing the shifting, shaking walls and see-sawing floors; no one else could hear the deep, sonic rumbling or sense the violent vibrations.

I was just having a "head quake" and everyone seemed surprise that I'd never had one before and they were amazed I'd never even heard of them.
