What does dreaming about a serpent (snake) mean in the Bible?

From Eden onward the serpent stands for temptation and the deceiver himself. Yet Scripture also holds the strange mercy of the bronze serpent lifted in the wilderness — Jesus' own picture of His cross. A snake dream may expose a temptation or lie at work; it also points to the One who crushed the serpent's head. In the SoulGuide Dream Guide, serpent is filed under animals — one of 54 symbols in the guide — and is answered with 3 King James Version passages quoted in full: Genesis 3:1, John 3:14, Matthew 10:16. Each passage below carries a short note explaining why it applies to serpent, so the entry can be read on its own without the rest of the guide.

“Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?”

“And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:”

“Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.”
