Do animals dream?
Research conducted by various scientists show that animals do experience dream while sleeping. They also experience similar sleep stages like human beings - REM and Non-REM. If you have noticed a dog sleep, it might sometimes wag its tail, this indicates some response to its dream. A study was conducted in a cat by removing a part of the brain stem, which will not prevent it from reacting to the dream during REM. It was noted in some cats they were aggressively chasing mice as in reality.
Dreams reflect our actions that we have already performed. Most of us have dreams activities relating to our past life. One of the common dreams that every individual has gone through is their experiences during the school life, where you would get images of teacher hitting you, making you feel numb and shameful.
