Cathisophobia is the fear of sitting. Do you know of any strange phobias?
In my opinion any phobia is an abnormal fear. That is why it is called a phobia even strange. A fear of the same sex or just having sex would be a phobia. Another common phobia would be that of children. That and a fear of child molesters popping out in the dark. All of these are abnormal phobias caused by the television and psychology. Other phobias are caused by life experiences. Such as a fear of sitting might go back to early childhood when one had to sit on tiles as a discipline.
