There cannot be the slightest doubt that the wish-dream, in its simple or what Freud calls its infantile form, represents an extremely common type of dream.[160] A large number of the dreams of children are concerned with wishes and their fulfilments. Those dreams of adults which are aroused by actual organic sensations also tend to fall, though not invariably, into the same form. Again, we chance to want a thing when we are awake; when we are asleep we dream we have found it. It may also be said, almost with certainty, that in some cases our dreams are the fulfilment of unexpressed and unconscious waking wishes. Even the best people, it is probable, may occasionally dream of events which represent the fulfilment of wishes they have never consciously formulated. Archbishop Laud was accustomed to note down his dreams in his Diary. On one occasion we find him setting down a disturbing dream, in which he saw the Lord Keeper dead, and 'rotten already.' A little later we find that Laud is 'much concerned at the envy and undeserved hatred borne to me by the Lord Keeper.'[161] It is not difficult to see in the Archbishop's relations to the Lord Keeper an explanation of his dream. If, however, wishes, conscious or unconscious, are often fulfilled in dreams, and if, as we have seen reason to conclude, symbolism is a fundamental tendency of dreaming activity, it is inevitable that wish-dreams should sometimes take on a symbolic form. It is thus, for instance, that I interpret my dream of being in an English cathedral and seeing on the wall a notice to the effect that at evensong on such a day the edifice will not be illuminated, in order to avoid attracting moths; I awake with a slight headache, and the unilluminated cathedral was the symbol of the coolness and absence of glare which one desires when suffering from headache.
