People who claim to be nondreamers
A. have much less REM sleep than other people.
B. rarely have penile erections.
C. sometimes recall dreams if awakened during REM sleep.
D. typically have more REM sleep than other people.
The correct answer and explanation is:
The correct answer is: C. sometimes recall dreams if awakened during REM sleep.
People who claim to be nondreamers are individuals who believe that they do not dream or do not remember their dreams. However, research suggests that even those who report not having dreams may still experience them, particularly if they are awakened during the rapid eye movement (REM) sleep stage, which is when most dreaming occurs.
REM sleep is a stage of sleep where brain activity is high, and this is the time when vivid dreams are most likely to occur. Although these individuals may not recall their dreams upon waking, they can sometimes remember them if they are awakened during REM sleep. This is why some nondreamers might still occasionally report dreams, but generally, they have lower dream recall.
On the other hand, the idea that nondreamers have less REM sleep than others (A) or more REM sleep (D) is not supported by scientific evidence. REM sleep patterns do not significantly differ between those who report dreaming and those who claim not to dream. Additionally, the presence or absence of penile erections during sleep, which is a normal physiological response, is not related to whether a person reports dreaming (B).
In conclusion, the key factor for nondreamers is not the absence of dreams altogether, but rather the difficulty they experience in recalling dreams after waking. This is often a result of how the brain processes and stores memories of dreams, with some individuals simply having a lower capacity for dream recall.
