Step-by-step explanation:
Sleep Disorders There are several sleep disorders that can cause short episodes of unconsciousness. One example is narcolepsy, which involves an irresistible urge to fall asleep during waking hours. Narcolepsy can be triggered by emotional situations, such as laughter or anger. Another sleep disorder is sleep apnea, where individuals stop breathing during sleep. This can be triggered by factors such as obesity or a narrowed airway. Lastly, night terrors can also cause short unconsciousness and are often triggered by stress or tiredness.
