It seems that most demons are in some way associated with serpents.
I’m really trying to see what people have seen for demons with serpent forms! (Mostly Samael and Leviathan!!)
I had a pretty distinct vision of an insanely long but thin dusky grey serpent in a tree, his body was positioned in sort of a strange way that made it not look like a reptile from afar. As I approached, it brought its head to me and the head was more dragonlike up close than snakelike. I had no fear, leaned in and kissed the serpent who immediately sprung out of the image to “do my bidding” in a masculine demon voice.
From my research it could really be Leviathan or Samael (or I suppose even Azazel as he has been called the serpent in the tree as well).
I’m just trying to identify the spirit (and maybe build a reference guide for future encounters!). I haven’t worked expressly with either yet but would like to honor the spirit that blessed me with this vision.
