Dream reproductions, whether in a symbolic form or not, are too common to need further statement. I would merely point out that the frequency with which childhood’s experiences occur in dreams is further evidence of the conservation of these early experiences. The symbolic dream, cryptic or obvious, deserves, however, special consideration because of the data it offers to the problem of the nature of conservation which we shall later study. In this type of dream, if the fundamental principle of the theory of Freud is correct, the content is a symbolical continuation in some form of an antecedent thought (experience) of the dreamer.[24] When this thought, which may be forgotten, is recovered the symbolic character of the dream, in many cases, is recognized beyond reasonable doubt.[25] If this principle is well established, and nearly all investigators are in accord on this point, though we need not always accept the given interpretation of individual dreams—if the principle is sound, then it follows that symbolism includes memory of the original experience which must be conserved. So that even this type of dream offers evidence of conservation of experiences for which there may be total loss of memory (amnesia). Before closing this lecture I will return to the point which I temporarily passed by, namely, the significance of the _difference in the form of reproduction_ according as whether it is by automatic writing or through associative memories in abstraction. In the latter case, as we have seen, the memories are identical in form and principle with those of everyday life. They enter the personal consciousness and become conscious memories in the sense that the individual personally remembers the experience in question. Abstraction may be regarded simply as a favorable condition or moment when the subject remembers what he had at another previous moment forgotten. We have seen also that the same thing is true of remembering in hypnosis (excepting those special realistic reproductions when the subject enters a dream-like or somnambulistic state and lives over again the past experience in question). In automatic writing, on the other hand, the reproduction is by a secondary process entirely separate and independent of the personal consciousness. In the examples I cited the latter was in entire ignorance of the reproduction which did not become a personally conscious memory. At the very same moment when the experiences could not be voluntarily remembered, and without a change in the moment’s consciousness, something was tapped, as it were, and thereby they were graphically revealed without the knowledge of the subject, without memory of them being introduced into the personal consciousness, and even without the subject being able to remember the incident after reading the automatic script. Even this stimulus failed to bring back the desired phase of consciousness. It was very much like
