A Japanese toymaker claims to have invented a gadget that can help people control their dreams.

Tokyo-based Takara Co says its Dream Workshop can be programmed to help sleepers choose who or what to dream about.

In a study on a group of men and women aged 20 to 40, it had a success rate of 22% in inducing dreams in which one of the prompt words appeared, said the Yomiuri Shimbun.

While preparing for bed, the user mounts a photograph on the device of who should appear in the dream, selects music appropriate to the mood and records word prompts, such as a name.
