Well, either my google-fu has failed me or this is a red herring.
Is there some creepypasta out there about people working in a deep sea habitat going violently insane, in the same vein as the Russian Sleep Experiment? Something, something…Atlantis? Cthulhu? The Bends? I can only guess.
Or did someone think The Abyss movie is a documentary?
On the other hand, deep sea exploration is pretty scary. Physically there’s the risk of the bends, high-pressure nervous syndrome, or just explosive decompression. Not to mention just getting stuck on the bottom of the sea with no one coming to rescue you.
You don’t even have to go deep to get into trouble – I’ve always been creeped out by stories of lost scuba divers.
SEALAB I, II, and III were experimental underwater habitats developed by the United States Navy in the 1960s to prove the viability of saturation diving and humans living in isolation for extended periods of time. The knowledge gained from the SEALAB expeditions helped advance the science of deep sea diving and rescue, and contributed to the understanding of the psychological and physiological strains humans can endure. – https://en.wikipedia.org/wiki/SEALAB
