I think being stranded out in the middle of the ocean is intimidating. Whether a killer shark is after you, maybe the boat or ship is haunted. I’ve watched the game boy color game, Resident Evil Gaiden, and that game really sets the bar to me as to how scary being in the middle of nowhere in the ocean can be. With packs of zombies on board and a deadly bioweapon as well, with no way out.
Stuck fast, upside down in a narrow pass in a cave.
This is from a real incident, where someone perished. They were an expert caver.
I can’t look up the story or read about it again.
My heart goes out to that person, their family and friends. Just one of the saddest events.
