Like most phobias I think most people experience discomfort with this imagery but to really have a phobia it needs to be an unreasonable level of anxiety I think.
IDK why we have a hard wired aversion to these. It might be a vestigial response to some kind of predator or danger which is no longer relevant.
I think that it disgusts me and makes me extremely uncomfortable. I would avoid it at all costs and I would probably freak out if I wound up unknowingly close to it. It is a weird type of fear. I can't explain why but my body will insist I stay far the hell away.
Were you to wake up one day with something like this in the skin of your leg (it can happen), I think you would realize why it can become a phobia 🤣 Also, I hope that never happens!
Those vile frogs where the babies hatch out of the back of the mother. Do I have this phobia, or is that also the most unnerving thing YOU've ever seen?
