All humans dream while sleeping even if they don't recall dreaming. We dream for two to three hours each night but 90% of the dream is lost in the first minute of waking. This may be a good thing because dreams are not usually happy but tend to be full of fear, anger, anxiety and sadness. Here's wishing you sweet dreams.

About Dreams

Dreams are successions of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep. The content and purpose of dreams are not definitively understood, though they have been a topic of scientific speculation, as well as a subject of philosophical and religious interest, throughout recorded history. The scientific study of dreams is called oneirology. Scientists believe that, in addition to humans, certain birds and the majority of mammals also dream.
