There are few things in Scottish mythology as feared and terrifying as a Kelpie.  Kelpies are shape-shifting aquatic monsters which haunt rivers, lochs and the sea.  A Kelpie is known in the Gaelic as an Each Uisge, which is literally a water-horse. The stories of Kelpies abound and come down to us from prehistoric times.  I go into this topic with a little bit of trepidation, and part of me even wants to avoid talking about it, because the myth of the Kelpie is something which chilled me as a child.  The window behind me is open wide, that's real thunder and lightning you are hearing behind me.  Thunder and lightning and a fierce wind just began happening as I began to speak about this, I am superstitious enough to wonder if we should even go there.  Coincidence to the non-believer maybe, but perhaps a sign to those schooled in the Arts and lore of the ancients.  Oddly enough the sound of a kelpie’s tail entering the water is said to resemble the sound of thunder.  Let's look at some recorded accounts of people encountering demonic Kelpies.
