This is a rather new thing for me to come across and I just fell the need to share this, a far few people have been talking about Shadow People being some kind of group or organization from Alternate realities, they are aliens, and the list can go on. Personally, I follow the alternate realities theory. So the question I ask, if these unusual beings are really from alternate realities and only seem to be observing us, why? Most people have said and push towards deep dark boggy men, with secret agenda waiting in the dark. Alright, so lets push the fear part aside, I myself can see two possibility: 1. Some how these shadow people can see into out reality and do so out of plain curiosity, I mean really if you could would you like to see into an alternate earth? 2. These shadow people are in fact not shadow people at all, but from out point of view they are. And to them we appear as shadow people to them. I don't wish to be drawn into the war of words here, but a number of event might make it possible to see the 'shadow' of an object, like a person from any number of alternate realities. These people simply do not react how we react when seeing them. I can see more possibility, but these are the main too I wish to share. The truth is that some things are just simple, only once you understand what you are looking at.
