Swirled vision is only fun in photos

This morning I developed a new symptom that I hope never happens again.  When I sat down to start my day of work early, I found that while looking at an Excel spreadsheet the grid seemed to swirl up to the right on an axis dead center of the screen.
I closed my eyes tight, relaxed them and opened them again.  Immediately the screen began to swirl on the axis again.  I shook my head, no relief.  I continued to close and open my eyes hoping for a deliverance from my swirled vision but none came.  I decided to lie down and go back to sleep for a couple of hours.  
When I awoke, my vision was fine.  It has been fine all day.  I have searched the web looking for something that might cause this phenomenon to no avail.  Will have to see if it happens again and try to notice other symptoms I may have experienced at the same time.  The Dr. is just gonna love this one.
