Description In: Five strangers board a descending lift, one by one, in a modern office block in London. They reach the sub-basement, though none of them have pressed for that destination. There they find a large, elaborately furnished room that appears to be a gentlemen's club. The lift door has closed; there are no buttons to bring it back, nor any other exit. Resigned to waiting for help, they settle down with drinks and talk. The conversation turns to dreams, and each man tells of a recurring nightmare.
