In the Den of Shadow People

I took this photo late last night at my place of work; it features a hallway leading to an area of the corporate center of the company I work with.  With a bit of editing, it is turned to an angle.  And in the area that is lit, there have been two encounters with shadow people by my fellow employees.

As I've mentioned before, I don't believe I have the ability to see the random energy that is about us; I don't believe that I have a "needle" to play out the energy around me to the extent to witness paranormal events.  Yet I have no doubt others do have the ability see play the "record" of energy about us.

Two incidents have happened in the area featured above that I am aware of; one incident involved a network/IT specialist who would have been seated directly to the left of the area above.  One afternoon, while working on a network issue after normal work hours, he witnessed two shadow people walking  from the foreground to the background on the lit hallway featured above.  Being on the left hand side of the hallway, the shadow people moved left to right from his perspective.  He immediately went to the area to find the people but had no such luck.

The second incident involved a customer service representative who worked one Saturday afternoon, again, after normal work hours.  She would have been seated at the very end of the hallway, directly to the right of the back wall.  She claimed to have heard children running around her that afternoon; footsteps of children running along the hallway to the back and to the near ground of the photo.  The following Monday, she had our IT group look at a video tape recording of the office (a security camera does record the entire area featured above); again no evidence was found of children in the office.  The video tape did show her "reacting to something"; the video tape did show her stand up from her desk, peer around the corner, and move around the office.  It was clear that she was looking for something.  Of course, nothing was found in person or in film.

I have heard several theories of the cause of shadow people; multidimensional beings, djinn, ghosts, alien entities, and mental projections.  Many more theories likely exist.  Yet I question again these premises; why does the experience need to have an intelligent or sentient root cause?  Why can't the incident simply be energy that manifests specifically to the observer and to the observer's sociological/psychological perspective?  Why does there need to be a romantic notion of other intelligences or previous life as being the cause for the phenomenon?  More specifically, why can't the energy being witnessed be random; better yet, why can't the universe be random?
