There are important purposes in dreams for someone who reflects. Such a person thinks about how "realistic" the dreams are that he sees while asleep, which in that way are no different in their realism from the moment he awakes. For instance, despite one person's body lying on the bed, in dream he went on business trips, met new people, and had lunch while listening to music. He enjoyed the taste of his meal, danced to the music, became excited because of the incidents that happened, became happy and unhappy, was afraid and felt tired. He could even have driven a vehicle that he had not previously driven until that day and did not even know how to drive.
So, you can experience, see, touch, hear and taste things that are not only real but also things that are unreal.
