Shadow is the reflection of something or some one.
Can there be a shadow without any form light?
I think the answer is NO or perhaps shadows in the dark can only happen in the mind. In the sense that, no matter how dark life seems to be, there is always an inner light that shines through the mind thereby giving you a reflection of your life either positively or negatively.
In this picture, I was trying to get the orderly placed pillars of my church's walkway but was surprised seeing my shadow instead, this is as a result of the sun that was shining from behind. Honestly, It took me some minutes before I could realise that it was actually my shadow😄
Isn't it funny, trying to hunt for others shadows but ended up capturing my own shadow.
You're welcome
