Necrophobia, is also known as Fear of Death and Fear of Dead Things. It is a surprisingly common phobia. If you have this phobia, you can suffer from panic attacks, and it may cause you to isolate yourself from your family and friends. Symptoms include: shortness of breath, rapid breathing, irregular heartbeat, sweating, nausea and an overall feeling of dread.
Your fear of dead things is created by your subconscious mind, and it is a defense mechanism that makes you avoid certain situations. Probably, sometime in your past, you experienced a moment when a death or seeing a dead thing caused you lots of emotional trauma. In other words, you probably had the stuffing scared out of you by some real-life brush with death or something dead! This may not always be the case, though, as some people experience this phobia after seeing something really grisly on TV or in a movie.
You may suffer from this phobia all the time, or you may only suffer if something triggers your fear, like a close call with a dead animal or the funeral of a loved one or friend. In any case, if this fear is getting in the way of your daily life, please seek professional help and/or counseling.
