PREFACE
There are at least four different ways of writing a book on dreams. There is, for instance, the literary method. In this way one goes to books or to the memories of other people for one's material, and so collects a great number of more or less wonderful stories. I have rejected this method, for it is entirely untrustworthy. Dreams are elusive at the best; only a very careful observer can set down a dream faithfully, even directly after it has occurred, and no one can safely entrust a dream to memory.
