Jack be Nimble and Humpty Dumpty. For Jack its the leap, but for me its the walk down the hall. When I overlay the dream against Humpty Dumpty, the feeling that some of the opportunities of the open window may be hard to reverse if I take them. Like Humpty Dumpty's unfixable pieces, I may not be able to return once I go down the hall or out the window. The nursery rhyme overlays have how opened up the dream image into two new areas that are in the dream image.
Further comparisons are sure to bring out more parallels.
B. Do the same thing again, but with Fairy tales. And finally, try this with a mythological story. If you are not familiar with myths, check the bibliography for Books on Myths and online resources. Often they are seen as primitive explanatory stories for the nature of the world. But as those who study Myths have found, they are also stories that weave sacred and profane meaning together on many levels.
