All my works, all my creative activity, has come from those initial fantasies and dreams which began in 1912, almost fifty years ago. Everything that I accomplished in later life was already contained in them, although at first only in the form of emotions and images.
Carl Gustav Jung

You know not what a book you seem, half read by lightning in a dream!
Dante Gabriel Rosetti, 1847

If the dream is a translation of waking life, waking life is also a translation of the dream.
René Magritte, belgian surrealist

Men tell me that sleep has many dreams;
but all my life I have dreamt one dream alone...
Dante Gabriel Rosetti, 1847

Dreams are brief madness and madness a long dream.
Schopenhauer

All men/women dream, but not equally. Those who dream by night, in the dusty recesses of their minds, wake in the day to find that all was vanity; the dreamers of the day are dangerous men/women, for they may act upon their whims and desires, dreaming with open eyes whilst making their notions possible.
T. E. Lawrence

Our normal waking consciousness, rational consciousness as we call it, is but one special type of consciousness, whilst all about it, parted from it by the filmiest of screens, there lie potential forms of consciousness entirely different. We may go through life without suspecting their existence; but apply the requisite stimulus, and at a touch they are there in all their completeness, definite types of mentality which probably somewhere have their field of application and adaptation. No account of the universe in its totality can be final which leaves these other forms of consciousness quite disregarded. How to regard them is the question - for they are so discontinuous with ordinary consciousness. At any rate, they forbid a premature closing of our accounts with reality....
William James

How often it has happened that I dreamed at night that I was by the fire, though I was quite naked in my bed! ... I am reminded of having been deceived by similar illusions while sleeping; and, lingering on this thought, I see so clearly that there is no certain index at all by which wakefulness can be clearly distinguished from sleep, that I am quite amazed and my amazement is such that it is almost capable of persuading me that I am dreaming right now.
René Descartes
