All that I can remember of this dream is that part of the dream took place outside, I was walking somewhere when I saw The Rock (Dwayne Johnson) teaching a man and a woman some exercises in and near a ditch and / or sunken area near a small body of water.
The Rock and the other two people were going up and down the ditch or hill doing lunges, stretches, and other exercises focusing on their form / technique & endurance; and The Rock was a good teacher, I maybe have briefly joined them, but I can not remember.
