Little Bruno has gone to sleep and will travel through dreams during the night. The mission of the dream guardians is to keep him immersed in pleasant dreams and ensure that he wakes up as little as possible.

The goal in Deep Dreams is to score points by playing and connecting dream cards that show the four dream colours. Players must create the largest connected colour groups to score victory points, while also making sure Bruno does not wake up by drawing a continuous path using the white lines and arrows through the cards. Some dream cards have powerful effects that help create better combinations. In the end, the longest path earns the greatest reward. Enter the world of dreams and ensure that Bruno enjoys a quiet and peaceful night.
