Thalassophobia has only stricken me on those rare occasions where you have really good visibility in daytime and floating over a coral shelf that drops off into the abyss. Into nothingness.

yup, I found looking into the abyss terrifying

so why isn’t it terrifying to look up into sky? Why don’t I get the same terror when I’m flying? It’s odd

maybe the abyss is a different world and that’s why it’s scary
