The concept of the dream is integral to understanding Surrealism and also plays a key role in unlocking the secret meaning of The Persistence of Memory.

For Surrealists, dreams were very important. A major goal of the art movement was to capture visually what it is like to be in the dream state. We have all had fantastic dreams where unrelated people, places, and objects come together in inexplicable and irrational ways. Understanding that The Persistence of Memory most likely relates to and depicts a dream state is the first step in revealing the hidden meaning of Salvador Dali’s mestery

Some art history scholars believe that Dali's melting clocks may symbolize Albert Einstein's groundbreaking Theory of Relativity, a new and revolutionary idea back in the 1930s. In his Theory of Relativity, Einstein proposed a new concept of time. According to Einstein’s theory, time is a relative and complex concept that cannot be tracked with such a crude, simple gadget as a clock or a pocket watch. In The Persistence of Memory, Dali’s clocks might be melting away because they are outmoded and losing power over the world around them. Limp and increasingly ineffectual.

The Persistence of Memory is arguably Dali’s most famous painting. Its iconic "melting clocks" have become an icon of Surrealism and one of the most recognizable pieces of art of the twentieth century. While the painting's true secret meaning is uncertain, Salvador Dali most likely knowingly encrypted all of these layers of historical, psychological, artistic, social and autobiographical meaning into his mysterious, enduring work of art. There may be even more layers of meaning hidden in The Persistence of Memory that we haven't found yet.
