Although I don’t dream ( or should i say i don’t remember my dreams ) as often as many people, I have many time wonder why we dream. There are so many explanation to this interesting experience that all of us have. Freud said that dream is to protect our sleep, to hold our attention so that we’re not woken from outside stimuli. Jung suggested that dreams may compensate for one-sided attitudes held in waking consciousness. Ferenczi proposed that the dream, when told, may communicate something that is not being said outright, etc… [src]. However, yesterday, I read an article on Psychology Today explaining yet another theory on dream. This time though, with an interesting experiment and rather logical explanation, the theory sounds more convincing to me.

==========================
A dream researcher at the University of Turku, in Finland, Revonsuo believes that dreams are a sort of nighttime theater in which our brains screen realistic scenarios. This virtual reality simulates emergency situations and provides an arena for safe training. As Revonsuo puts it, “The primary function of negative dreams is rehearsal for similar real events, so that threat recognition and avoidance happens faster and more automatically in comparable real situations.”
Faced with actual life-or-death situations—traffic accidents, terrorist attacks, street assaults—some people report entering a mode of calm, rapid response, reacting automatically, almost without thinking. Afterward, they often say the episode felt unreal, as if it were all a dream. Threat simulation, Revonsuo believes, is why.
