Quizplus · Accepted Answer

The swaying of the eyes from side to side beneath the eyelids is a characteristic of the rapid eye movement (REM) stage of sleep. This stage is also known as paradoxical sleep because the brain is active but the body is in a state of paralysis. During this stage, the eyes move rapidly and dreams occur. It is a normal part of the sleep cycle for infants and adults alike. The other options, hypersleep, ESP, and fMRI, are not related to the phenomenon described in the scenario.
