I was walking down the street tonight and I got a fright because I had 2 shadows (I thought one of them was a person! lol I got a fright). Why did I have 2 shadows? Was it the street lights? The moon? ...
You have two shadows when there are two sources of light hitting you in different directions. So yes, we all sometimes have two shadows. It's not supernatural, or any rubbish like that. :)
Two or more shadows means you're by more than one light.
