1) People who are born blind do not see any images, but have dreams equally vivid involving their other senses of sound, smell, touch and emotion.
2) Our mind is not inventing faces – in our dreams we see real faces of real people that we have seen during our life but may not know or remember.
3) Dreams speak in a deeply symbolic language. Whatever symbol your dream picks on it is most unlikely to be a symbol for itself.
4) The most common emotion experienced in dreams is anxiety. Negative emotions are more common than positive ones.
5) During REM sleep the body is paralyzed by a mechanism in the brain in order to prevent the movements which occur in the dream from causing the physical body to move.
