Was it a dream or an improv scene?

Is improv just a multiplayer dream? Both follow every whim by a player, only worrying if they make sense later. Both must keep going at any cost, no time to rest. No going back. Both tend to increase what is already there. A stressed dream will create ever more sources of stress, and improv is the same. Both often have nonsensical plots that take a background role behind emotions and characters.

This excercise is a test. Are dreams distinguisable from improv? I have compiled a list of dreams and improv scenes I can remember. Can you tell which is which?

Names have been added or changed in all the stories. My memory is imperfect so if you saw one of the improv plots or the dreams and spot a mistake, please let me know. You will be shown a random subset of the longer list of stories I compiled.
