Sleep is scarrier for women than for men.
A British study indicates that women's nightmares are more frequent, and more vivid than for men.
Women tend to dream more about being chased or threated, or about losing a loved one.
Men dream about being physically attacked more often. Both sexes dreams about the same when it came to pleasant dreams, although men tended to include more intercourse in their dreams.
The exact cause of the difference in nightmares remains unknown. But Parker says it could be due to a woman's menstrual cycle, or the fact that men, in general, don't experience as much deep sleep, which is where nightmares show up.
