Darkness
Darkness (when applied to our everyday world), is simply the absence of light. Everything is still where it should be, it simply isn't illuminated.
However, from a human perspective, the baggage that is associated with darkness can be quite harrowing.
Bad things happen all the time, it doesn't matter what time of day or night it is, but, and it's a big but, some humans have inbuilt associations with darkness that make it in some way seem threatening.
I am unfortunately one such person. I am hesitant when moving about in dim lighting conditions.
This hesitancy renders me completely terrified in pitch black areas and I am aware that this is purely baggage that I carry with me from my childhood. However hard I try I cannot master the fear imprinted upon me by my mother when I was just a young child.
To counter this irrational fear I carry a torch when I know I will be in darkness at some point. It isn't any old torch either, it is an American high power instrument constructed by Maglight, which dispels darkness, and thus my fears of it. God Bless Maglight.
