A gentleman wrote to Neville describing how, after neglecting a longstanding problem, he sat at his office desk one Tuesday and imaginatively constructed and rehearsed a scene implying the problem was already solved, replaying it until the voices and scenery 'began to become alive.' That night, as he continued the rehearsal while falling asleep, he dreamed he was a disembodied observer at a party celebrating a young man's unexpected good fortune, and at one point felt himself merge into the young man's own embarrassed gratitude before returning to being merely an onlooker.
