The paranoiac-critical method is a surrealist technique developed by Salvador Dalí in the early 1930s. He employed it in the production of paintings and other artworks, especially those that involved optical illusions and other multiple images. The technique consists of the artist invoking a paranoid state (fear that the self is being manipulated, targeted or controlled by others). The result is a deconstruction of the psychological concept of identity, such that subjectivity becomes the primary aspect of the artwork.
