Whenever I see or even hear of a gory and violent death that happens underwater, I feel disturbed by it for days. For example, I even cringed when I heard about that acid scene from the film Untraceable when I never even watched it. I get afraid when I see sharks feeding underwater. But when I see them on dry land I feel less disturbed. I even watched tons of incredibly gory shows and they didn't really disturb me. But when I think of graphic deaths underwater it really disturbs me. Is this normal?
