Dali used a technique called “hypnogogic imagery” to conjure up the extraordinary images in his paintings. He would put a tin plate on the floor and then sit by a chair beside it, holding a spoon over the plate. He would sit on a chair, holding a spoon over the plate. He would then totally relax his body. The moment that he began to doze the spoon would slip from his fingers and clang on the plate, immediately waking him to capture what he had just seen.
