Snakes appear often in dreams, and their significance may vary from positive to negative. Dreaming about snakes are as diverse as the snakes themselves, ranging from those concerned with constriction to those involving deadly bites, with many dreams centering on the water and others on the shadows. Some dangers don't reveal themselves until it's almost too late. Dreams involving snakes, like many dreams that appear to be vestiges of our evolution or indications of some fundamental Jungian unconscious, may be quite uncomfortable. Even though dreams have been around since the beginning of time, the context in which we interpret them now depends heavily on popular culture.
