Deirdre Barrett describes dreaming as simply /thinking in different biochemical state/ and believes people continue to work on all the same problems—personal and objective—in that state.[68] Her research finds that anything—math, musical composition, business dilemmas—may get solved during dreaming.In a related theory, which Mark Blechner terms /Oneiric Darwinism,/ dreams are seen as creating new ideas through the generation of random thought mutations.
