i sort of forgot one, but it is more of a fear of a combination of things.

it is the drop off of a ledge in a body of water that ends in darkness, like what you see people scuba diving off the edge of reefs near, when the reef ends and it just drops into darkness, it is a fear of darkness, heights(i feel as though if i were to be over the darkness i would just sink, not float) and of not being able to see the bottom of a body of water, that i would say is my biggest fear of all time
