We all dream at night. Some remember more about their dreams than others, but they are all 'interpretations' by the time one wakes up. Then some can tune Into their Dreams while they are happening. That is called Lucid Dreaming...and can occur more readily even by 'asking or telling oneself to become aware of when one is dreaming.
Over time and with practice 'tuning in', one may see quite a show...and even be able to direct one's dream towards 'landing on one's feet', flying on a magic carpet or eagles wings (a large eagle). Get the picture?
