The common phobia of point-like dense objects is that people will have instinctive fear of dense objects. For example, when they see dense flies, dense bees or even dense crowds, they will have symptoms such as cold back, itchy body and trembling all over. In general, punctate phobia does not need treatment, because it is a common human reaction.
Maybe the phobia of point-like dense objects didn't occur in the ancients, or the frequency was relatively low (after all, it was not easy to see tadpole egg lotus milk in ancient times ...). But the ancients must have it, because it is a normal manifestation of human beings (mild, severe is pathological)
