Quote from : Sleep Has His House Book

Foreword: Life is tension or the result of tension: without tension the creative impulse cannot exist. If human life be taken as the result of tension between the two polarities night and day, night, the negative pole, must share equal importance with the positive day. At night, under the influence of cosmic radiations quite different from those of the day, human affairs are apt to come to a crisis. At night most human beings die and are born. describes in the night-time language certain stages in the development of one individual human being. No interpretation is needed of this language we have all spoken in childhood and in our dreams; but for the sake of unity a few words before every section indicate the corresponding events of the day.
