I had my first real dream in a long time. I never dream and if I do I don't remember it or only bits and pieces later in the day when something would trigger my memory. I woke remembering my dream. Short version, it was about me holding a snake that my x husband was holding and it jumped on me. Trying to remove him, he bitten down on my thumb and another finger. I got him off and there was no bite marks. I felt him bite me. He was poisonous. I called 911 anyway. I was fine. Then I woke up. Right away I googled dreams, bitten by snake.... I was amazed 2 websites said the same thing.
It would depend on the association you had with the dream. Did you struggle with the snake or did it wither and die after it bit you? Gillian Holloway, Ph.D. identifies being bitten by a snake as meaning different things. She says, "In many dreams a single snake will come to bite you, and you may in fact be bitten after a brief struggle. To your amazement though, you will not die, and may find that the situation is not as bad as you thought." According to Holloway you have this kind of dream if you are struggling with some problem, relationship or challenge. "Such a snake-ordeal is an important signal that you are going through a kind of initiation; a psychological and spiritual trial that has the potential to change your life for the better if you deal with it bravely and with a clear heart. You may have to give up something you thought you couldn't, or take a stand for your principles or faith."
