Algernon Blackwood,
A Victim of Higher Space
(1914)
“ Certain people, certain human atmospheres, certain wandering forces, thoughts, desires even—the radiations of certain combinations of colour, and above all, the vibrations of certain kinds of music, will suddenly throw me into a state of what I can only describe as an intense and terrific inner vibration—and behold I am off! Off in the direction at right angles to all our known directions! Off in the direction the cube takes when it begins to trace the outlines of the new figure! Off into my breathless and semi-divine Higher Space! Off, inside myself, into the world of four dimensions! ”
