Image at the Window - Emma's Window

In a June 29, 2012 email from a member of a Ghost Hunting Society,  he states:

Emma reading a book.

Images captured in windows are highly unreliable as windows act as reflections and based on the angle of the observer the shadows in windows might be confused as being paranormal.  However, unless the full body apparition can be observed, not just a shadow, the odds are too great that the shadow is from a natural occurring source. 

Regardless of what we see here, our original photos from November, 2011 (Photos of Emma) are NOT just a shadow. The photos taken are a full body apparition! How exciting!

So, is Emma a ghost or a spirit?  One person thought she was more spirit than ghost because she appears to have looked up at the photographer in the second photo taken of her - meaning she REACTED to someone.  Whereas, a ghost, he explained, does not react or communicate with blood-flowing humans.
