Shadow People Reports Have a Para Normal Explanation

I don't see any evidence clearly pointing to them having an origin in another physical dimension. To me, this sounds like more speculation that's not supported by evidence. Even if something is non physical, that doesn't mean it can't affect physical objects. It may just be psychochinetic. Angels and demons are known to have this. And para psychologists have sought to demonstrate in the laboratory that it's a human ability as well.
