...there are those things that having looked at in vain I never dare to see, which are all the things I love (in their presence I no longer see anything else); there are those things that others have seen, and that by means of suggestion they are able or unable to make me see also; there are also those things that I see differently from other people, and those things that I begin to see and that are not visible.

(Andre Breton: Surrealism and Painting)
