And we often even have 4-7 dreams in one night. Blind people do dream. Although their dreams may not consist of vivid images, blind people can clearly recall and describe the sounds they hear or the textures they come in contact with in their dream. Their hearing and tactility are hyper-sensitive. Five minutes after the end of the dream, half the content is forgotten.
Men tend to dream more about other men, while women dream equally about men and women.
Studies have shown that our brain waves are more active when we are dreaming than when we are awake. Dreamers who are awakened right after REM sleep, are able to recall their dreams more vividly than those who slept through the night until morning. Physiologically speaking, researchers found that during dreaming REM sleep, males experience erections and females experience increased vaginal blood flow - no matter what the content of the dream. People who are giving up smoking have longer and more intense dreams. Toddlers do not dream about themselves.
