These past events tend to develop phobias which are the fears of any specific thing or an experience. Any stories told to a child can result in phobias which will haunt him for lifetime. .
People also develop fear after knowledge. A person gets older and gets a clear view and knowledge of the surrounding. After all the experiences, he knows what is good and what is bad. He can differentiate what is safe and what can be dangerous. A person automatically fears when he sees a gun because of his prior knowledge that guns are dangerous and it hurts people. This creates the panic and anxiety. Except the probable physical dangers, a person can also experience fear mentally. A person can make up his mind into believing something to be dangerous that is actually not dangerous. A child knows that the room is empty but he fears to turn off the lights. It's just his state of mind. Mentally, a person can also experience emotional fears. Any situation which can affect the person's emotional status can cause an emotional fear. That fear when a child goes to school for the first time, that fear when a girl introduces his boyfriend to her parents, that fear when a student experiences when he has to go in the front of a class to give a presentation, all are the examples which are caused by the knowing the emotional effects or probable embarrassments.
