Great post Mike sadly a lot of people think you can't be spiritual without making the religious connection.
Strange lights is where the term jack O lanterns origiated they were seen near some civil war camps...not sure how far back the sightings or the term goes.
This one was near Corinth Mississippi.
"This is where I first saw a jack o'lantern (ignis fatui). That night, while Tom and I were on our posts, we saw a number of very dim lights, which seemed to be in motion. At first we took them to be Yankees moving about with lights. Whenever we could get a shot we would blaze away. At last one got up very close, and passed right between Tom and I. I don't think I was ever more scared in my life. My hair stood on end like the quills of the fretful porcupine; I could not imagine what on earth it was. I took it to be some hellish machination of a Yankee trick. I did not know whether to run or stand, until I heard Tom laugh and say, "Well, well, that's a jack o'lantern.
