There is a common myth that Snakes are often portrayed in a wrong way. The serpent came in form of snake and deceived Adam and Eve. The dreams are usually pretty complex and they are multi-layered. Snakes might indicate sexual energy in our dreams but they are seen for other reasons too.
If snakes appear in your dreams, it is a sign of a personal transformation. There is a change in healing and it is an initiation. They make you anxious and it is a chance for you to move forward. 'Snakes on Grass' indicates that you should not trust anyone.
And on an interesting note, this also means you should not trust yourself. You may have made some decision by trusting yourself, just reverse it. A snake which comes after hibernation can show that you have free flow of energy. In 'Eastern' culture snakes in dreams were termed as 'Kundalini'.
This is an energy which coils up from the base of the spine to the crown of our head. But above all most dreams are just laid already in our unconscious mind and they are response to our own present and past events.
