Answer:
d. Jasper is experiencing physiological changes that are normal during REM sleep.
Explanation:
Rapid Eye Movement Sleep (REM), also referred to as paradoxical sleep, is a state of sleep in the normal sleep cycle, which involves active movement of the muscles of the eyes, and the diaphragm, as well as increased brain activity. However, the skeletal muscles are relaxed. This type of sleep is characterized by vivid dreams as brain activity is intense, although there is absence of no motor function during this sleep.
We can conclude that, the physiological changes experienced by Jasper are normal during REM sleep.
