The vibration idea is probably true. I had a similar experience myself
several years ago, in a 'past life' working as a sound engineer. The studio
I was using had some *very* large speakers, whose response reached down
substantially below 20hz. I was working on a mix for a track that had some
seriously thwompy bass, created by tuning several synthesizers octaves apart
to create subharmonics. Anyway, I worked out later that some of those
subharmonics would have been at around the 8 - 14hz frequency range. I was
mixing quite loud, and it was indeed creating an 'elated' feeling. After
half a day or so, however, I was taken ill. It felt like a cross between
extremely bad motion sickness and a bad stomach bug - it took me out for
something like three days. A couple of weeks later, I did some more work on
the same track, and ended up with identical symptoms, and another 3 day
absence.

The effect is definitely real, and *not* nice. At that point, I started
using a 20hz filter on the crossover driving the monitor speakers - the
problem never happened again.
