Suddenly I became possessed of a kind of augmented sight. Over and above the luminous and shadowy chaos arose a picture which, though vague, held the elements of consistency and permanence. It was indeed somewhat familiar, for the unusual part was superimposed upon the usual terrestrial scene much as a cinema view may be thrown upon the painted curtain of a theatre. I saw the terrain we had traversed, the machine, and the unsightly form of Levitz opposite me; but of all the space unoccupied by familiar objects not one particle was vacant. Indescribable shapes both alive and otherwise were mixed in disgusting array, and close to every known thing where whole worlds of alien, unknown entities, flabbily quiverring in the twisting machinations of spacetime encompassing us. The scene was wholly kaleidoscopic and in the jumble of sights, sounds, and unidentified sense-impressions I felt that I was about to dissolve or in some way lose solid form. The creatures were present in loathsome profusion, but my attention was diverted elsewhere as a wild indescribable keening rent the fabric of space: There in the centre, a vortex of sound and motion began to form, spreading outward an inky blackness studded with unnatural constellations. Formless entities writhed and burbled on the other side to the frantic piping of insane flutes...
It is at this point that I lost consciousness and remember no more.
