Abstract

A group of 1,324 spontaneous psi experiences of the precognitive type was compared with a group of 1,966 contemporaneous cases as to the forms of expression (such as dreams, intuitions, etc.) found in each and their frequencies of occurrence. Qualitatively, the two groups were the same except for the reference of the experiences to present or future events. There were, however, striking quantitative differences in the frequency of occurrence of different forms in the two groups. Dreams, particularly realistic ones, predominated among precognitive experiences; whereas intuitive and hallucinatory experiences were most frequent among the contemporaneous group. The findings are presented for their suggestive value for a further experimental attack on the parapsychological problems involved.
