Abstract
Cessation of dream recall has been reported in numerous neurological disorders including multiple sclerosis (MS). Two women MS patients are presented in whom transcranial treatment with AC pulsed electromagnetic fields (EMFs) of 7.5 picotesla flux density restored dream recall and 4 to 5 months later induced vivid colored dreams. The experience of colored dreams coincided with a period of distinctive improvement in visual acuity, color vision, and depth perception and in one patient with normalization of the visual evoked potential latencies. Dreams associated with REM sleep are reported to be vivid, colorful and lengthy and administration of melatonin facilitates REM sleep and increases its duration in humans. Additionally, melatonin administered at night induces vivid colored dreams in normal subjects and narcoleptic patients. Therefore, since melatonin secretion is sensitive to the effects of pulsed EMFs these findings suggest that the experience of colored dreams in these patients was probably related to reactivation of the pineal gland with increased nocturnal melatonin release. The recurrence of colored dreams in the course of magnetic therapy may be a marker of pineal regeneration.
