Absolutely true.  It's happened to me exactly twice.  The first time was on
my first night dive.  It was on a wreck and I knew there was a spiny sea
urchin close by (because I saw it).  A bit of surge caught me just enough to
bump my rear end against something.  Fear or having an ass full of spines
during a live aboard trip caused me to move rapidly and, for a very brief
moment, lose all orientation.  Because I was close to the wreck, I
reoriented by sight quickly and easily, but that doesn't mean my heart
wasn't beating quickly.

The second time was also on a night dive.  This time on the Nickolson,
directly out from Sunset House on Grand Cayman.  A mystery meat sandwich and
a high speed run to meet the tourist sub at the wreck did unpleasant things
to my stomach which payed me back by emptying itself somewhere between 60
and 80 feet.   I not only didn't know which way was up, I didn't care.  When
things were a bit calmer, reorientation was again easy.  This time Jayna and
I both had rapid heart beats.

Uh Oh.  Now I'm in trouble.  I don't wear a weight belt in warm water
anymore.  Guess I'll just have to watch my bubbles.

Also an excellent story, but you're going to have to embelish it a bit if
you're going to sell it.

Substantial snip.

While I certainly agree, my personal navigation is mostly natural.
Currents, distractions and just plain fate make precise compass navigation
unreliable where I dive most, but you may reasonably assume that I know the
boat's generally north (or other direction), the shore generally west, which
way the bottom drops off in the area and how deep it is where the boat is
anchored.  Since it's usually my boat and, no matter how hard I try, it
won't come and get me unassisted, it's a good thing.  Perhaps this is the
reason I once passed on a couple of dives just because it didn't feel right.
It was in current at the tip of the Toungue of the Ocean, off Nassau.  There
was no land anywhere in site and the closest islands were too small to count
on finding by fin power alone.  Jayna and I both sat out an afternoon and an
evening dive at the site.  I suspect that, lacking an opposing current, I
could swim as long as necessary to reach land, but I have to know which way
land is to do it.
