One of Belfast's oldest former churches has been transformed into a powerful new immersive art experience for the next six weeks.

Carlisle Memorial Church is now hosting Dreamachine, where audiences lie back and close their eyes for a performance of sound and white light.

The experience has been described as both highly personal and collective, with every participant seeing something different, before getting an opportunity as a group to share what they saw through words and drawing.

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.

The free experience follows sold-out shows in Cardiff and London, and runs in Belfast until 4 September.

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.

Participants enjoy an immersive experience with light and sound

Jennifer Crook, director of Collective Act, said the best description of the experience is that it cannot be described.

"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 like a light show, but inside your mind. You might see colours, patterns and shapes. Some people see lots of kaleidoscopes, other people see real-world scenes, almost dream-like scenes but you won't know until you see for yourself."

"One of the most beautiful parts of the project is the drawing table, this is the space where you're invited to reflect on your experience, and draw it or write about it or even just discuss it with others around the table.

"You never know what people are going to say, you never know what they saw and it's an endlessly fascinating conversation to listen and learn how individual people's experiences are."
