Do animals dream?
According to electroencephalograph recordings of sleep states in animals, it is possible to believe that some animals dream.
Rapid Eye Movement (REM) sleep, the 'dreaming sleep', has been reported in most studied mammals, for example, rats, cats, monkeys, elephants and birds.
Among mammals, only the echidna does not have REM sleep. Since REM sleep is not recorded in snakes and other reptiles, some scientists suggest that REM may be a process related to warm-blooded animals. REM sleep occurs once every 90 minutes in human beings, and about once every 25 minutes in cats.
Dogs do dream because many owners have witnessed their dogs panting, whining and moving their paws while sleeping - obvious signs of dreaming.
