Psychoanalysis shares fear and phobia (fear). You can be afraid of darkness, enclosed space, spiders, injections, even foreigners, but the cause of fear is incomprehensible; fear is not caused by this or that object or event, but by an incomprehensible danger "that one must discover." When we are dealing with fear, we can not say what exactly we are afraid of, since it arises for no apparent reason. But this does not mean that there is no reason at all, and there is no escape from fear.
Fear.
Unlike phobia, fear does not perform any protective function. If the phobia reminds of a danger from which it is necessary to defend, i.e. activates your potential and makes you make the right decision. And fear, on the contrary, shows "helplessness before the form of danger." It does not allow us to correctly assess the situation and make the right decision, and in many cases endangers life itself.
