I saw Inception, I think there is a bug in it:

Supposedly, the mind experiences 50 years in some dreaming state (a dream within a dream within a dream..) in an hour or so.

Yet every experience of the mind, dreaming or not, must at the end reside on the function of the brain. Can the brain as a biological entity process informations of 50 years in an hour without conflicting its capacity and the physiology of the rest of the human body?
