So, if we add all of that up:
Snakes represent rebirth and transformation, as well as intellect, intuition, eternity, immortality, Kundalini, expansion of consciousness through divine intoxication, etc.
Snakes and Dragons are both considered reptilian and are closely associated throughout history, dragons in some cases being referred to as āwinged serpentsā. Dragons being associated with: The Devil or adversary, power, chaos, sovereignty, creation and destruction, and passion. Beast par excellence if you will.
So, there we have powerful alchemical symbols. We also have the changing of seasons, winter to spring, much like in the myth of Persephone, who is led out of the underworld (winter) by Hekate, a goddess associated with snakes, the color silver, and dragons. She is led to Demeter by her (spring)
8 is associated with transformation, wealth, authority, infinity/source (I suppose), and cycles. (Changing of seasons can be considered a cycle too)
We also have silver, a lunar element and color. Hekate is also associated the Moon. Bar Hekate, it is also associated with Alchemy, etc.
Finally, what I would argue that we have here, is the ending of the dark night of the soul. Once withered things that died in the cold winter are now going to be rebirthed into the spring. However, I do think that this also means that I would be taking on more Adversarial/āDevilā qualities, like I did in my Devilās Hoof dream (Lilith was apart of that who is considered Lunar and a Serpent related deity).
