The low amplitude, irregular wave patterns and the presence of eye movements under the eyelids are both characteristic of REM (rapid eye movement) sleep, which is associated with dreaming. The twitching of the hands and feet is also a common occurrence during this stage of sleep. Therefore, the researcher can conclude that Cliff has just entered REM sleep.
