This quote from Strindberg’s A Dream Play, that was used as the closing line of Fanny and Alexander. He is referring to dreams, but I think it applies to the creative process as well.
“.. på en obetydlig verklighetsgrund spinner inbillningen ut och väver nya mönster; en blandning av minnen, upplevelser, fria påhitt, orimligheter och improvisationer.”
… which translates as
“… on an insignificant base of reality the imagination spins out and weaves new patterns; a mixture of memories, experiences, free inventions, absurdities and improvisations.”
This picture is of a window in the 18th century dairy at my grandparents’ farm near Kalmar, Sweden, a constant source of inspiration for me.
