The following is an abstract from a paper by M.A. Persinger and S. Krippner.
"The 24-hour periods in which the most accurate telepathic dreams occurred during the Maimonides studies displayed significantly quieter geomagnetic activity than the days before or after. This statistically significant V-shaped temporal sequence in geomagnetic activity was not evident for those periods when less accurate dreams occurred. When geomagnetic activity around the time of the strongest experimental telepathic dreams was compared to the geomagnetic activity around the time of spontaneous telepathic dreams from the Gurney, Myers and Podmore (1886) collection, very similar (statistically undistinguishable) temporal patterns were observed. Analyses of both experimental and spontaneous telepathic experiences indicated that they were more accurate (or more likely to have occurred) during 24hour intervals when the daily average antipodal (aa) index was approximately 10 ñ 3 gammas. When the daily aa index exceeded amplitudes of approximately 20-25 gammas, telepathic experiences became less probable."

Comment. It must be added here that mainstream science does not (yet) admit that telepathy exists as a legitimate scientific phenomenon. Nevertheless, there is an immense literature on telepathy and related parapsychological subjects. Once again we have a "shadow science," with its own journals, conferences, and research institutions - all outside the fold of mainstream science.
