What does the snake mean in dream interpretation?

Dreams communicate through symbols which have unique meaning for each individual dreamer. To one person, a snake could represent "a snake in the grass," that is, someone or something that is not to be trusted. But to another dreamer, the snake could suggest the caduceus, the symbol of medicine and healing. Alternatively, at this time (December 2010,) a python might be seen in dreams after seeing the recently released Harry Potter movie, "The Deathly Hallows, Part 1," in which the python Nagini is vividly portrayed.

It usually means that there is a fortune in your future! Which means you can see more money in the future!:)

Are they nightmares? If so, it may mean you are afraid of them. If not,well.....the answers vary. Have you watched any movies on snakes lately or read a book that had snakes in it?Did you go to a zoo and saw snakes and perhaps you cannot seem to forget them? If you believe this is serious, discuss the matter with your family and/or friends. They may be able to help you with your mystery.

Dreams are a function of the subconscious.

Symbols have different meanings to different social groups. It therefore depends on the group to which you belong what those symbols mean.
