"I can't tell, I think we're upside-down."

This gives me a horrible feeling in the pit of my stomach.

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?

If you're in cloud, you can't see out. When flying, you can generate g
forces (by turning, banking, climbing, etc) which can fool you into
thinking that "down" is in any direction. So, it's quite easy to not
know where up and down are. I suppose it's like being deep underwater,
but for different reasons.

This is one of the first things one must learn in instrument flying -
trust the instruments over your inner ear. They are less likely to be
lying to you.

...and it's what I always thought was the actual purpose of the minimal
instrument flying taught in the PP curriculum, that is, you can't do it
without reference to the instruments. Second lesson is, that in
anything but momentary, smooth IMC, you can't do it without more training.

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.

The Poison Theory

The poison theory attempts to provide an explanation for why motion
sickness and cybersickness occur from an evolutionary standpoint. The
theory suggests that the ingestion of poison causes physiological
effects involving the coordination of the visual, vestibular, and
other sensory input systems. These physiological effects act as an
early warning system which enhances survival by removing the contents
of the stomach.
