Phobias: Musophobia and Nyctophobia

Phobia is a persistent and irrational fear of a particular type of object, animal, activity, or situation.
Musophobia. Musophobia is a fear of mice and rats. The reason for this fear could appear because of the person’s past traumatic experience with mouse or rat. Examples of this could be having a house or room invaded by them, finding them eating food, being surprised when they jump from a trash can, touching them while getting up as they run from under furniture, smelling them or getting sick from them.
The symptoms of Musophobia vary by person depending on the level of fear. They typically include extreme anxiety, dread and anything associated with panic, such as shortness of breath, rapid breathing, irregular heartbeat, sweating, nausea, inability to articulate words or sentences, dry mouth and shaking. These symptoms can occur just by seeing them on TV or in a room, while someone is joking about them, or smelling them. However, everyone experiences their fears in different ways, such as screaming, running to different rooms, or getting to higher ground.
Even though, there is some medicine for this fear, but they do not cure Musophobia. Medicine can provide a temporary effect. This fear should be treated by counselling, hypnotherapy, psychotherapy and Neuro-Linguistic programming.
Nyctophobia. Rational fear of the dark is good for us, which can produce caution and alertness for the natural danger of darkness. But this fear becomes as a phobia, called Nyctophobia, when a person feels an extreme and irrational anxiety response to darkness even if he knows he is safe, like in his bedroom. However, Nyctophobia is more commonly problem in childhood, because of a little experience. While in adults it can occur because person has not faced that fear before or for some bad darkness experiences in the past.
Symptoms typically include nausea, sweatiness, disorientation, loss of control and even panic attacks. Treatment with anxiety medication is often recommended for cases when frequent panic attacks and lose of sleep occur. However, medicine should be accompanied by psychological therapy. Sometimes a night-lamp can help. Many people have this phobia and even Indian Nationslist Mahatma Gandhi also suffered from it.
