Delta waves are typically associated with deep sleep, which occurs during stage 3 and 4 of NREM (non-rapid eye movement) sleep. Stage 4 is characterized by predominantly delta waves, and it is the deepest stage of NREM sleep. The confusion and disorientation upon awakening from stage 4 is also typical due to the grogginess associated with deep sleep. Therefore, the most likely stage of sleep in this scenario is stage 4 of NREM sleep.
