Dean,
Where do they come from? We can assume
anything 'till we find out. Could it be from some
kind of invisible entity, from a different dimension,
that still has the ability to mutilate? We don't know
for sure; up above, from down below, or on this
plane, but manifest from time to time from another
dimension. Wherever they are from they make
a nice mess before they leave.
