Lucid dreaming is a technique where a person in a dream state is fully aware that they are in a dream and can actively control whatever happens in a dream.
Empath: The Luckiest Smurf stories[]
In the EMPATH: The Luckiest Smurf story series, telepaths such as Psyches usually have this ability in the sense that they can enter a "dream space" with a bonded Psyche. Dreamy Smurf, a non-telepath, has also developed the ability of lucid dreaming through an artifact called the Heart Of Sominess.
Glovey stories[]
In the Smurf Me Up series, Glovey adapts to lucid dreaming, being aware he is asleep as he concentrates in his dreams to control how they go in The Red Mist story with the help of Dreamy and Lazy, who both claim to be in control of their dreams.
