link between cubism and surrealist art

Max Morise was the one that suggested that cubism was very much alike surrealism, he came to the conclusion that cubism was another version of drawing in the unconscious min, in other words automatic drawing. synthetic cubism was also thought as automatism, as a way of placing the ready made as part of the picture relying thoroughly on the painters imagination. surrealist's said that there was hardly any difference between the cubism collages of Pablo Picasso, Georges Braques and the dream collages of Ernst.
Pablo Picasso synthetic cubism:

 Ernst dream collage:

two very different art styles looking pretty much the works of the same artist. the difference been that surrealists enjoyed landscapes in there pictures unlike cubism which was mainly based around portraiture. Picasso replied that hes work wasn't automatic, he went on about how automatic drawing can be a way of saying hes work was done by chance, but he said that it was all down to hes creative mind and just chance that synthetic cubism ended up looking like dream painting.
