The Human World
A Mysterious PlaceEven though the creatures of Halloween are dependent on humanity for their survival, they don't actually know too much about human day-to-day existence! Any knowledge they have tends to be visceral and instinctive: head for dark places, be creepy, and
scare. Outside of this, general knowledge of human culture is relatively scattered. (Think of the Wizarding World in the Harry Potter books: wizards only awkwardly understand Muggle culture, and even have special Muggle Studies classes. Halloween Town creatures are the same way towards humans.)
Naturally, there are a few
special beings in Halloween Town (not students!) who know a great deal, either through personal experience/research or by collecting that information from others. Students at Amityville Academy may take Human Studies courses... of course, it's anyone's guess as to how
truly accurate the information presented there actually is.
There two things about the Human World that are well-known and taught to all aspiring students when appropriate: the first is that the Human World is naturally resistant to FEAR. If you don't possess enough FEAR to start with, you will not be able to affect anything in the Human World - you won't be able to touch objects, and humans will not even be able to see or hear you! Beings with very little FEAR, such as minipets, may not be able to survive in the Human World at all. For their own safety, children and lower-level students are not permitted to enter the Human World.
The second thing is that the Human World has a strange version of
day that involves a massive light billions of times brighter than Halloween's own pumpkin sun. This hideous orb is called the
'sun', no pumpkins involved, and its light can be inimical to some Halloween species, burning them on contact. The light of the 'sun' also appears to empower humans and make them less vulnerable to scaring.
While Halloween Town creatures can go out during the Human World day, they do so at their own risk. Scaring during the day is so much more difficult that very few creatures actually try it - however, those who can pull off quality Day Scares are considered Master Scaresters!
Travel to the Human WorldThere are many doors to the Human World in Halloween Town, and each door gives the user a choice of many delightful locations. Haunted houses, shadowy closets, eerie caves, spooky woods, hospitals - any place that often gives humans the creeps is capable of creating a doorway back to Halloween. Where a creature prefers to haunt/hunt/harvest depends on their species: ghosts may have special haunting grounds passed on like family heirlooms, while monsters have a special talent for lurking under beds and in closets.
These doors are
all guarded and regulated by the Boogeymen, Halloween Town's police force. The Human World cannot be entered without going through one of these doors, and to do so you must have a passport. Passports are required both to enter the Human World and to get back to Halloween!
Losing your passport in the Human World is a
very bad idea. Without a passport, you can't get back into Halloween Town, leaving you stuck in the Human World until someone notices you're missing! This may take a
really long time - indeed, some of the truly long-lasting haunts and monsters seen over the years in the Human World are a result of creatures being irresponsible with their passport.
Student movement between worlds is monitored very closely, so it's rare for them to have to wait more than a day or two for a rescue. Nose Goblins are not allowed into the Human World except on carefully supervised field trips.
