The pain of parting is nothing to the joy of meeting again. Nicholas Nickleby

That which had grown from the earth, to the earth, But that which has sprung from heavenly seed, Back to the heavenly realms returns. This is either a dissolution of the mutual involution of the atoms, or a similar dispersion of the unsentient elements. Book VII

There is a kind of sleep that steals upon us sometimes , which, while it holds the body prisoner, does not free the mind from a sense of things about it, and enable it to ramble as it pleases. So far as an overpowering heaviness, a prostration of strength, and an utter inability to control our thoughts or power of motion can be called sleep, this is it; and yet we have a consciousness of all that is going on about us, and even if we dream, words which are really spoken, or sounds which really exist at the moment, accommodate themselves with surprising readiness to our visions, until reality and imagination become so strangely blended that it is afterwards almost a matter of impossibility to separate the two. Oliver Twist
