A dream is a series of ideas  images, emotions, and sensations which generally happen unwillingly in the mind in certain stages of sleep. Dream is dependent on the condition and situation of the human beings in their life. If an individual is a student then he dreams for good marks then he dream to get good marks with first position. If any individual is jobless and unmarried then he dreams for job and married life so the examples make it clear that the mostly dreams are dependent on the situation of life of a person. Some people see unexpected dreams related witch or other types.

The dreaming occurs in individuals during REM (Rapid Eye Movement) sleep which most animals also experience. The director of Evolutionary Neurobehavioral Laboratory at Boston University says that as mammals experience REM (Rapid Eye Movement) sleep, it is reasonable to suppose that animals have some thiny like we call dreams.

Scientists and experts are not sure that animals sleep. Many pet owners have seen their sleeping dogs or cats pull jaws with sudden jerk as if they are seeing eatable things such as mice or bone. After around 20 minutes, a dog enters REM (Rapid Eye Movement) sleep, which is the stage of dreams. As per experts, they say that big dogs sleep longer. Small dogs have sleep frequently and quickly. Fish and Insects do not experience REM (Rapid Eye Movement) sleep.

In short, we can say that it is yet to find out whether animals dream like us.
