Hey, Rumplstiltskin, Ive been meaning to get back to you and get back on here for a while. Hah. Anyway, to answer your question, to think of Jason as my double or not would be but a creation of mind that is based on something intangible. Ive had another encounter that more closely matches the idea of a skinwalker, and i will post that into a new thread into the Double section. Remember that we each have unique ways of being touched by the unknown.  I would be interested to hear any experiences you have had related to skinwalking.
