Yeah, it happens a lot. Some events in the series are absurd and make no sense. But that's because of our lack of understanding or because of the alien ways things work in some worlds.
Characters have a vary different anatomy than ours. I mean, how would you expect a living organ to function? Some entities see us as multiple organs that weirdly enough don't work on their own. The're are also non-matter organs that even we have, but don't perceive them. More info on the subject here.
Tied with perception and how our feelings and mind affect it. In the series we encounter characters, objects and places that have a different art style than the rest. From doodles, cartoony, realistic, photographic, photoshoped, pixelated, 3D and other styles, it's something about how we can perceive it.
Awakened and UnawakenedEdit
The term awakened may refer to those that became aware about the zones and such. Most non-human characters are like this while most humans are unawakened.
Simply refers to what type of lifeform a creature is. It isn't limited to just what be call organic, bioforms can be animate objects and anything else that doesn't have organic matter.
Bleed or Leak (Zonal)Edit
A zonal leak is when some element or concept from a zone gets in an another zone. Leaks can create connections between zones, like when Burgrr bleed into The Hospital. Another example is the concept of The Hospital leaking into the grey zone creating pseudohospitals (the real world hospitals).
Blogs and JournalsEdit
Some characters have personal blogs and journals. The way they write them is totally alien to us, as they can update even when they shouldn't be able to, no matter in what situation they are. You can see the link to a character's blog on its wiki page.
Branches and BranchinationEdit
While zones have an infinite number of layers, which are similar to alternate timelines, entities have a finite number of branches. Branches are like those timelines where you exist, and some of them end with your death. Humans normally have a single branch, meaning that their death is permanent. Other entities can generate (or germinate) new branches, a process called branchination.
Written words are often misspelled. Some entities also speak with broken grammar and gibberish. That's because their language is imperfectly translated for us.
Are mentioned often and have quite the meaning. Cones can be similar to body parts and on some occasions are referred to as an entity. "The cone was lied before, and it could lie again."
Everything exists out of concept. The first step for something to exist is to be conceptualized. Then, from the concept, it can manifest a concrete form. Entities and zones alike are born from concepts. Only from conceptualizing a thing you already make it happen somewhere.
In the most general sense, consciousness is an ability of some living object to perceive and recognize the surrounding reality.
The center of every being and the primary concept of its own existence. Cores connect to concepts with their branches, and one core can lead to multiple beings. For more information, read this book.
Now why would we need one of those? In Awful Hospital, Phage speaks directly to the readers, in addition to the fact that Fern is controlled by them. Fern has also snapped at the commentators twice, once without actually knowing what they were and once snapping a suggestion box in half and yelling at them.
See сoncept above.
Possible conditions of a certain zone, which all beings inside constantly move through. For humans, this movement is straight and linear, forming experience called "time". For nonhumans it can by quite different. Instantaneous jumping to distant layer is also possible - in this case new layer will look like a completely another "timeline".
Parasitic cores. Can't branchinate by themselves and need another cores to manifest themselves into reality.
Spirals and SpiralingsEdit
