[Revalidation of the Saul and Sheppard "Dream Hostility Counts" in a time series of 24 dreams, of which 7 ended in a migraine at awakening].

Our Series of 24 dreams can be used for validating hostility scales. Nocturnal migraine represents an ideal archimedian point (C. G. Jung) from which psychology can reach certainties comparable to those of physics. By Pearsons Phi coefficient psychological findings can be solidly moored to the "non-psychical", the somatic sphere. Revalidation of the Dream-Hostility-Count lead us to a higher degree of significance (p < 0.005 instead of p < 0.01) than that reached by Saul and Sheppard who used hypertensives for a critical group.
