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.
Improving memory can be done in a number of ways, and one of those is by having a good night's sleep. During sleep, your mind is still busy and going through the process of consolidation, where it strengthen your memories as well as the "practice" skills, which you have learned while you're awake. According to the associate professor at NYU Langone Medical Center, Dr. Rapoport says that something happens while we are all sleeping, and it helps us learn things better. Thus, if you're trying something new, you can perform it better right after you sleep.
