Van de Castle has noted that earlier onset recurrent dreams are more likely to be disturbing while later onset recurrent dreams are more likely to be pleasant. There is also a category of dreams that Freud called typical dreams that may be highly recurrent although people may not report them as such. Apparently Freud's interest in recurrent dreams was only that they served as evidence that dreams contain impressions from childhood that do not appear to be accessible to waking memory. Jung attached far more significance to recurrent dreams than Freud. Also to Jung's credit, when he had finished interpreting his recurring house dream to his own immediate satisfaction, he said that he never dreamt about it again. The traumatic recurrent dreams appeared to dissipate and change into ordinary dreams over time, and did so more quickly with group therapy. A spontaneous recurrence of the traumatic dreams was also observed when new stressors like divorce entered the picture.
