Shadows are supposed to be something that is after you. When the sun shines or when you are in front of light.
The shadows are always behind or beside. Day after day, stories after story, tales after tales. Shadows are now being linked with something that is very wrong. Something dark, something like your past, something that is haunting you. Shadows now have a different meaning. Shadows are not something that is that evil, though people have come to see the evil in almost everything that exists on this earth. Or Shadows are not Shadows doesn’t fall under the categories of evil things.
In fact. If we are going to see the story that surrounds Shadows is always from medieval tales and some African folklores.

This is hard to see any trace of a shadow being used negatively either in. The Bible or the Quran? I don’t really know where the starting point of Shadow Story being evil started from. I wouldn’t even bother to ask. But if ever there is an evil side of shadow. I’m sure it will be a myth. There is no evil in seeing your own shadow by yourself. Is just a part of life something that must shows that you are a living being and you are not a spirit. Spirit are the only ones that I know that doesn’t have a shadow and that leaves us is another tails on his own.
