, as we all know, are very queer things: some parts are presented with appalling vividness, with details worked up with the elaborate finish of jewellery, while others one gallops through, as it were, without noticing them at all, as, for instance, through space and time. Dreams seem to be spurred on not bybut by , not by the head but by the , and yet what complicatedmy reason has played sometimes in dreams, what utterly incomprehensible things happen to it!
