Description from the publisher:

Dreams can be vivid, as if they're actually happening — but when they end, they can be hard to remember. With a little luck, and some careful communication with friends, a dream can be something that's cherished forever.

Dream On! is a collective storytelling game in which players create a dream together. Using the dream cards, they have two minutes to create a dream story. When the timer runs out, they then have to remember what happened in the dream and in what order. They score points for getting the details correct. At the end of the game, they tally up their score to see how much of their collective dream they've remembered.
