Dream research has evolved through three historical periods. The first began with Freud's 1900 'Dream Interpretation' and lasted until the 1950s. The second started with the discovery of REM sleep in the 1950s and extended to the 1990s, during which some neuroscientists viewed dreams as meaningless by-products, exemplified by Hobson's activation-synthesis hypothesis. Cognitive psychology in this period showed dream characteristics could be measured and were regular. In the third period, from the 2000s onward, neurological evidence revealed dreaming is not unique to REM sleep, shifting debate to dreams' psychological meaning. Recent empirical research demonstrates dreaming regulates emotions, consistent with psychoanalysis.
