Theory of MultiDreams, written by author and poet Jean-Philippe Cazier (born 1966), is a work of fiction loosely inspired by the contemporary astrophysicist Aurelien Barrau's work on "Multiverses" and by the stories of H.P. Lovecraft.

The book entwines astrophysics and fantasy literature through fiction, deconstructing the frameworks of narration, logic, identity, space and time.

The story commences with the disappearance of one of its characters, developing a kaleidoscopic narrative in which identities proliferate, when dreams become the means for travel through space and time and in which Lovecraft himself seemingly becomes one of the characters.

Theory of MultiDream charts a troubling voyage in which science and literature converge to create a paradoxical universe that is nonetheless real--or was it merely dreamed? But who said dreams weren't reality?
