AJ13 – Thanks to Christine for being so helpful, I can only add a couple of things.
You are moving toward a big event, but it may take a while for it to materialise.
What you carry into the dream is important; you carried the sense that the snake will bite if not held firmly. The snake is part of your brain – see http://dreamhawk.com/dream-encyclopedia/brain-levels-and-dreams/#reptilebrain
– and it is very powerful influence. What you carry into a dream is what creates the action, so of course you got bitten.
The thing is that you had it all in the ‘palm of your hand’. Sometimes we meet the pain we have created through our attitudes – the hedgehog. I know that sound a bit hard, but I have found it rue over and over. So try being the snake and the hedgehog and see what you make of them - http://dreamhawk.com/dream-encyclopedia/acting-on-your-dream/#Being
