Subnautica can cause, cure, and worsen, Thalassophobia.

It somehow did all 3 to me

Thalassophobia (from Greek thalassa θάλασσα, "sea", and phobos φόβος, "fear") is the persistent and intense fear of deep bodies of water such as the sea, oceans, or lakes.

I have thalassophobia

I tried watching a playthrough of subnautica

I only watched 20 minutes of it

Yup i have that and subnautica made it worse

i dont have thalasaphobia
and subnautica made me abselutely fearless to the ocean
