Well Colette you had just been reading all our posts, so it does sound to me as if it was probably purely a reaction to that. As for the Devil, covered in blood, well if there was any message from your great grandparents, you know what relatives can be like when they're over here - "Why do you want to know?" "It's none of your business" etc - I am sure some of our relatives on the other side are probably just as awkward about family history as those this side of the Great Divide! My personal feeling is that there was no message in this particular dream, it was just your mind going over what you had read. Perhaps in your subconscious, the devil and blood are simply symbols of physical death. I personally believe very strongly, in fact I take it as read, that death is not the end and we do go on. I think your great-grandparents are probably happily progressing with their spiritual development, if they have not already come back to earth to continue their growth.
