The medical field still has not admitted Trypophobia as a defined disease,
it's not in the dictionary, and it wasn't on Wikipedia until just recently.
Although it's not known why these images cause unpleasant sensations in some people and not in others,
the scientists are certain that Trypophobia does not have a cultural origin,
as triskaidekaphobia does, for example.
If you feel like you identify with the situations described above, then your Trypophobia is really a true phobia
and it would be a good idea to seek help so that your symptoms don't interfere with your life.
