My girlfriend see's shadow people when she is awake 2 or 3 times a day?

Tell your girlfriend to ignore them and they will eventually fade away.

Before I can tell you why, I need to know a few things. First, is she seeing them from her peripheral view or straight on? Second, to what degree is she able to descride them? Finally, is it always in the same location (such as in her house) or anywhere she goes?
