Acrophobia Treatments and Causes
Achluophobia is a pretty common fear in its roots because it is actualy a fear of the dark but with a sppecific cause.
Fear of the dark is of course nothing uncommon and in some cases can make a lot of sense because when one of your senses, which is the sense of vision is supressed there can be a natural reaction.
Fear of the dark is also called Nyctophobia.
Normally Achluophobia starts a child and there is often no point iin life that a person can go back in time to realise when the trigger was.
