What are the 10 weirdest or most curious phobias?

Phobias are one of the most common psychological conditions today, at least three quarters of the world’s population claims to have some type of phobia. These are characterized by expressing excessive and uncontrollable fear of an object, situation, activity, animal or any other point of origin. When a person comes into contact with what they fear the most, they usually show reactions such as trying to run away, scream, cry and even faint.

This is an irrational phenomenon that occurs in a particular way in each person, however it is possible to identify some elements in common. In this way, it has been possible to give a name to each of the phobias that until now are considered the most common. However, some of them are classified as the most curious or rare , due to the particularity of the reason of origin why a person feels fear. That is, in some cases it attracts a lot of attention because it may be considered as something not very credible or even a subject of ridicule.

Exposure to the stimulus that generates the phobia immediately provokes a response of anxiety and distress . People are able to recognize this situation however they cannot have control over their protective instincts. Only what they perceive as dangerous will generate such reactions, they also understand how unconventional and strange their fear is.
