Two hypnosis professionals from France, Kevin Finel and Brice Battung, are looking to transform spa relaxation experiences with their Dream Machine innovation.

"In a world that's moving ever faster, it's sometimes difficult to disconnect, to take time for yourself, to refocus on your feelings and emotions," say Finel and Battung.

Already offered at Paris' iconic Molitor Hotel Spa, the Dream Machine uses patented photostimulation technology – an approach typically used in neuroscience laboratories.

It's a lamp which emits various flickering patterns of light to stimulate the optic nerve and then the brain in a sensory spectacle.

"Your brain becomes the director of breathtaking images ... filled with vibrant colours and complex geometric shapes."

An app proposes 27 sessions and four programmes which control different "light dances" depending on how users want to feel. They've been designed to help calm the nerves, aid meditation, enhance concentration, improve sleep or even induce a psychedelic experience.
