Leprechaunophobia is the fear of leprechaun. Many sufferers of this phobia believe that leprechauns are evil and may attack them just like it happens in Leprechaun movies, which means they would stay inside their residence while leaving all the outside doors locked at all times (unless it’s someone they know of course). Sufferers would be deeply distressed if one even sees the image of leprechaun on a paper or screen.
Leprechaunophobes would also fear St. Patrick's, called patricophobia, and would therefore hate the month of March.
