It would seem, too, as if they came out of Dreamland, as the children in TIECK'S story did out of Fairyland, with new lives.

This is, indeed, a beautiful conception, and I may remark that I will in another place comment on the curious fact that we can add to and intensify ideas by thus passing them through our minds in sleep.
Just by the same process as that which enables us to awake at a given hour, and simply by substituting other ideas for that of time, can we acquire the ability to bring upon ourselves pre-determined or desired states of mind.

This is Self-Suggestion or deferred determination, be it with or without sleep.

It becomes more certain in its result with every new experiment or trial.

The great factor in the whole is perseverance or repetition.
