B. The Material of Dreams- Memory in Dreams
That all the material composing the content of a dream is somehow derived from experience, that it is reproduced or remembered in the dream- this at least may be accepted as an incontestable fact. Yet it would be wrong to assume that such a connection between the dream-content and reality will be easily obvious from a comparison between the two. On the contrary, the connection must be carefully sought, and in quite a number of cases it may for a long while elude discovery. The reason for this is to be found in a number of peculiarities evinced by the faculty of memory in dreams; which peculiarities, though generally observed, have hitherto defied explanation. It will be worth our while to examine these characteristics exhaustively.
To begin with, it happens that certain material appears in the dream- content which cannot be subsequently recognized, in the waking state, as being part of one’s knowledge and experience. One remembers clearly enough having dreamed of the thing in question, but one cannot recall the actual experience or the time of its occurrence. The dreamer is therefore in the dark as to the source which the dream has tapped, and is even tempted to believe in an independent productive activity on the part of the dream, until, often long afterwards, a fresh episode restores the memory of that former experience, which had been given up for lost, and so reveals the source of the dream. One is therefore forced to admit that in the dream something was known and remembered that cannot be remembered in the waking state.[9]
Delboeuf relates from his own experience an especially impressive example of this kind. He saw in his dream the courtyard of his house covered with snow, and found there two little lizards, half-frozen and buried in the snow. Being a lover of animals he picked them up, warmed them, and put them back into the hole in the wall which was reserved especially for them. He also gave them a few fronds of a little fern which was growing on the wall, and of which he
