Aversion to happiness, also called cherophobia and fear of happiness, is an attitude towards happiness in which individuals may deliberately avoid experiences that invoke positive emotions or happiness. One of several reasons why cherophobia may develop is the belief that when one becomes happy, a negative event will soon occur that will taint that happiness, as if punishing that individual for satisfaction. This belief is thought to be more prevalent in Eastern cultures.
Claustrophobia is the fear of confined spaces. It can be triggered by many situations or stimuli, including elevators, especially when crowded to capacity, windowless rooms, and hotel rooms with closed doors and sealed windows. Even bedrooms with a lock on the outside, small cars, and tight-necked clothing can induce a response in those with claustrophobia.
Fear of the dark is a common fear or phobia among children and, to a varying degree, adults. A fear of the dark does not always concern darkness itself; it can also be a fear of possible or imagined dangers concealed by darkness. Some degree of fear of the dark is natural, especially as a phase of child development.
