As he bathed and changed clothes he tried to recall what he had dreamed after the scene in the violet-litten space, but nothing definite would crystallize in his mind. That scene itself must have corresponded to the sealed loft overhead, which had begun to attack his imagination so violently, but later impressions were faint and hazy. There were suggestions of the vague, twilight abysses, and of still vaster, blacker abysses beyond them—abysses in which all fixed suggestions were absent. He had been taken there by the bubble-congeries and the little polyhedron which always dogged him; but they, like himself, had changed to wisps of mist in this farther void of ultimate blackness. Something else had gone on ahead—a larger wisp which now and then condensed into nameless approximations of form—and he thought that their progress had not been in a straight line, but rather along the alien curves and spirals of some ethereal vortex which obeyed laws unknown to the physics and mathematics of any conceivable cosmos. Eventually there had been a hint of vast, leaping shadows, of a monstrous, half-acoustic pulsing, and of the thin, monotonous piping of an unseen flute—but that was all. Gilman decided he had picked up that last conception from what he had read in the Necronomicon about the mindless entity Azathoth, which rules all time and space from a black throne at the centre of Chaos.
