Dark Shadow Figures

What are dark shadow figures, are they demons that terrorize us in
our rooms late at night or just shy spirits that we only see out of
the corner of our eyes?   The answer is complicated, but
I've had a few encounters with these paranormal entities, and I
feel this question is way more complicated then most people think.
