Oneirology is the scientific study of dreams. Current research seeks correlations between dreaming and current knowledge about the functions of the brain, as well as understanding of how the brain works during dreaming as pertains to memory formation and mental disorders. The study of oneirology can be distinguished from dream analysis in that the aim is to quantitatively study the process of dreams instead of analyzing the meaning behind them.
