Shadows -argh so hard to write about-

Shadows are pretty neat. Scientifically shadows are just an area of space that a light source cant reach. Thinking like this nigh time is like a blanket of a shadow, but then that makes no sense because the moon+stars make a pretty good light. Hmm maybe at night its possible for a shadow within a shadow? Just rambling on now =(
When I was little i always thought of my shadow as my personal friend/stalker (to me same thing). It seemed to always follow me, and i would play games with my shadow like trying to run away from it or trying to trick it. Unfortunately my shadow is super smarter then I am so yea.
At another point in my life i used to think it was the opposite me who lived on the inside of the Earth. That i was probably his shadow if the world was inside out pretty crazy idea but i think it would make an awesome novel. Although it would be pretty bland if everything was a shade of black. More recently I have been looking into multiple dimensions and how very possible it is that multiple realities could be happening in a area of space we cannot perceive, which makes me think back to the days of my alternate me (shadow) and our many adventures.
A lot of cultures and people think of shadows as evil beings. Which in a sense shows what they think of themselves if a shadow is a part of you. I can think of a few reasons as to why some people might think of this. The thought of a dark being following your every step in the day and suddenly disappearing at night is a pretty scary thought. People with more open minds or even simple ones often love there buddy who seems to never leave them alone.
