Japanese scientists have designed software capable of taking images from dreams and processing them into images on a computer screen.
The team at the ATR Computational Neuroscience Laboratories produced the device by focusing on the image recognition procedures in the retina of the human eye.
So far the technology can only reproduce simple dream images, but the potential is there to unlock more complex dreams.
The study investigated how electrical signals, produced and sent to the brain by the eye's retina when it recognises an image, are reconstructed into images by the brain.
It is the first time scientists have been able to produce images directly from brain activity.
