Strange thoughts on the idea of horizontal elevators. Of course, the mechanics of it, as well as the economy of walking a corridor, render the idea ludicrous. Yet, why do I so often dream of entering an elevator that moves horizontally? It seems reminiscent of slow-motion running, another favorite of dreams (but more often nightmares). Another theme that seems to recur in dreams are sexual scenarios. Why do dreams take a fancy to certain scenarios? I mean, surely all of us would have had some recurrent dreams. Do they signify an unsatisfied desire? A hidden longing? A suppressed lust?
