Jungian psychology and the dream world both make prolific use of language puns. Symbolically, Rabbit in the Underworld is therefore representative of using one's intuition: knowing how to get around "in the dark" and being comfortable traveling in "unmarked territory." By default, it can also denote having or developing trust in the "Inner Light." Rabbit does not need an outside source to illuminate his way. His connection to the Collective Energy maintains his pathway.
So... you're saying my affinity towards the symbol of a a rabbit means i have an inner light that guides my way, and also means I am very comfortable going out on a limb...by golly - I think you're right!
