Some common Halloween myths include that Halloween is a prime opportunity for bad people to poison children or sex offenders to kidnap children and that it is one of the most expensive holidays and on par with Christmas. Another popular myth is that vampires are real, which is easily disproved by the fact the entire human population would be converted within only a few years.

A major myth, that strangers are out to poison kids with Halloween candy, has never materialized, according to Live Science. The only known cases occurred in 1974 and 2008. The child's father perpetrated the 1974 poisoned candy incident for life insurance money. In 2008, cold medicine appeared in a box of Smarties, but no one was harmed.

No more child sex crimes occur on Halloween than take place on any other day of the year, notes LiveScience. The real danger is child pedestrian accidents, as nearly six children die every Halloween due to impacts with cars. This is an increase from other days of the year.

Another myth, that people spend nearly as much on Halloween as they do on Christmas, is also false. While Halloween brought in $8 billion in 2012, Christmas dwarfed that by about $580 billion. In fact, Mother's Day, Father's Day and Valentine's Day all bring in more money than Halloween.
