Sweet dreams are made of geomagnetic activity

Looking for an explanation for recurring nightmares of leaving the house without your trousers on or losing your teeth? New research suggests you can blame the Earth's magnetic field, rather than a repressed childhood.

Darren Lipnicki, a psychologist formerly at the Center for Space Medicine in Berlin, Germany, found a correlation between the bizarreness of his dreams, recorded over eight years, and extremes in local geomagnetic activity.

Other studies have tied low geomagnetic activity to increases in the production of the melatonin, a potent hormone that helps set the body's circadian clock. So, based on anecdotal evidence that melatonin supplements used as a sleeping aid can cause off-kilter dreams, Lipnicki wondered whether local magnetic fields could induce the same effects.
