Dalí would sit in a chair, wrists dangling over the edges of the armrests. In one hand, he would grip a heavy metal key between his thumb and forefinger. On the floor, directly underneath the key, he would place an upside-down plate. Dalí would close his eyes and relax. The moment he drifted off to sleep, his grip on the key would release. Clang! Dalí’s eyes would snap open.
