Dreams have influenced important scientific discoveries and innovations. Famous scientists like Robert Louis Stevenson, Niels Bohr, and Rene Descartes were influenced by their dreams, with Descartes keeping a detailed dream journal. While dreams can seem nonsensical, remembering and analyzing them using techniques like dream journaling and free association can help solve problems by revealing new perspectives and ideas hidden in the subconscious. The key is learning to initiate and remember dreams in order to glean useful insights from their combinations of people, objects, and impossible scenarios.
