Delta waves are associated with Stage 4 sleep, which is also known as slow-wave sleep. This stage is characterized by deep, restorative sleep and it is difficult to rouse someone in this stage. Stages 1 and 2 are lighter stages of sleep, while REM (rapid eye movement) sleep is associated with heightened brain activity and dreaming.
