Displacement
Few experiences embody it as well as flying. This spoken by a land mammal. The sensation of coursing through the, air, above the clouds, ripples through the core with amazing terror.
One can only imagine the change in belief structure that must occur when flight is at your fingertips, or more likely, wingtips. Where the sky is indeed the limit and the fear of falling never sinks its primal teeth into delicate flesh, such freedom must convey a spatial rapture beyond reckoning.
I have flown in my dreams and not only were they some of the most memorable adventures, but they are also the ones I would relive most readily.
