"I made some inquiries about Mr Herbert Lewis's dream before I left Cardiff. He had been searching throughout the room in which the order was found. His theory as to how the order got in the place in which it was found is that it was probably put there by someone (perhaps with malicious intent), as he does not see how it could have fallen so. "The fact that Mr H. Lewis is exceedingly short-sighted adds to the probability of the thing which you suggest, that the dream was simply an unconscious act of memory in sleep.

Now, it seems to me in the above case that the dreamer's subliminal self may have taken note of the lost landing-order without his super-consciousness being aware of it, and that the fact returned to him in his dream. In R. L. Stevenson's "Across the Plains" may be found a striking chapter on dreams. It contains an account of some of the most successful dream experiments ever recorded. Stevenson's dreams were of no ordinary character; they were always of great vividness, and often of a markedly recurrent type. This faculty he developed to an unusual degree--to such an extent, indeed, that it became of great assistance to him in his work. By self-suggestion before sleep, we are told, the great novelist would secure "a visual and dramatic intensity of dream-representation which furnished him with the motives of some of his most striking romances." But "R. L. S." is not the only one who has secured assistance of dreams. Here is an account given by a German, Professor Hilprecht, of an experience of a similar nature ("Human Personality," i. 376):
