Carlisle Memorial Church is now hosting Dreamachine, where audiences lie back and close their eyes for a performance of sound and white light.
Some report witnessing a kaleidoscope behind their closed eyes, with others describing a rainbow of different colours, shapes, scenes reminiscent of a sepia film and the dappled effect of sunlight on water. It was created by Collective Act, bringing together Turner Prize-winning artists Assemble, Grammy and Mercury-nominated composer Jon Hopkins and a team of technologists, scientists and philosophers.
"The Dreamachine is an artwork you experience with your eyes closed but it's completely different for everyone that comes through because the experience is generated by your brain, it's different even each time you come," she said.
It's called 'Falling Asleep on the NiteLink'.
