What is the definition of a dream?

A dream is a period of time during which a person is temporarily transported to another place or time. It is a state of consciousness in which the individual is not aware of their surroundings and can experience a wide range of sensations, thoughts, and emotions.

The definition of a dream is also subjective and can vary from person to person. Some people believe that dreams are only real if they are vivid and memorable, while others believe that dreams can be more abstract and non-vivid.
