Sorry for the stupid question, but how on earth is this possible? Can't
you tell if you're upside down or not? Or is it like being deep
underwater?

The way it was explained to me once is you have your own instrumentation
in your head that is similar to the attitude indicator in an airplane.
However it has to reset it's self quite frequently or it sends your
brain wrong information. When you are flying in the clouds, with out a
visual indication of what is up and down, your internal attitude
indicator gets out of calibration in just a few minutes or less (can't
remember how long). Then regardless of the feel of g force which could
be in any direction when flying, your now out of calibration internal
attitude indicator keeps telling your brain what it thinks is up which
is most likely wrong.
