A book or song or movie or any other work has its respective introductory outwork or overture, something that frames and contextualises what follows in a more or less light or heavy way. One might assume that experiencing has something similar, a sort of metaphysical overture compressed into an out of time moment that tells you what realm of being you are to find yourself in - is it waking or dream, life or death? - it need not be correct, it only offers a starting point, a set of initial conditions, an ontological key-frame, but since consciousness or awareness has no gaps, cannot have any gaps but its nature, this need not be so. This is why oblivion is always possible, there is no seam in reality that you can get hold of in passing. A lot of what you seek to do in the everyday poetics of experience is to imagine or recreate such a seam. It is a work which is done not given.
