Which of the following is now widely considered to be the most accurate dream theory? Possible Answers: Dreams are the result of random electrical firings in our brains in regions that process memories. Correct answer: Dreams are the result of random electrical firings in our brains in regions that process memories.
Explanation : The most pervasive theory of dreaming is that dreams are a result of electrical impulses in our brains that occur only while we sleep.
Who was originally responsible for creating the psychoanalytic approach to dream theory? Possible Answers: Allan Hobson. Correct answer: Sigmund Freud. Explanation : Sigmund Freud is the founder of dream theory. Which belief was commonly held by ancient or older civilizations in history? Possible Answers: Dreams are portals to an entirely different world we cannot access in waking life. Dreams are unnecessary and frivolous, and should be ignored.
Correct answer: Dreams are portals to an entirely different world we cannot access in waking life. Explanation : Many older civilizations believed that dreams were metaphysical experiences wherein the soul was transported from the body to a completely different realm or spiritual plane. What is the difference between the physiological and psychological theories of dreaming? Possible Answers: Physiological theories claim that dreams are a product of neural firing in the brain. Correct answer: Physiological theories claim that dreams are a product of neural firing in the brain.
Explanation : Physiological theories claim that dreams are a product of neural firing in the brain, which can sometimes, according to some theorists, aid in the process of learning. Bed wetting and night terrors occur during which stage of sleep? Possible Answers: Stage 1. Correct answer: Stage 4. Explanation : Stage 4 sleep is referred to as delta sleep, or deep sleep. Possible Answers: Sleep apnea. Correct answer: Sleep apnea. Explanation : Sleep apnea is characterized by pauses or lack of breathing when sleeping.
Possible Answers: REM, using delta waves. Correct answer: REM, using theta waves. Explanation : Memory is encoded during REM sleep. Many people covet lucid dreaming and seek to experience it more often. Lucid dreaming has been compared to virtual reality and hyper-realistic video games, giving lucid dreamers the ultimate self-directed dreamscape experience.
Potential training methods for inducing lucid dreaming include cognitive training, external stimulation during sleep, and medications.
While these methods may show some promise, none have been rigorously tested or shown to be effective. A strong link has been found between lucid dreaming and highly imaginative thinking and creative output. Research has shown that lucid dreamers perform better on creative tasks than those who do not experience lucid dreaming.
Stressful experiences tend to show up with great frequency in our dreams. Stress dreams may be described as sad, scary, and nightmarish. Experts do not fully understand how or why specific stressful content ends up in our dreams, but many point to a variety of theories, including the continuity hypothesis, adaptive strategy, and emotional regulation dream theories to explain these occurrences.
Stress dreams and mental health seem to go hand-in-hand. While there are many theories for why we dream, more research is needed to fully understand their purpose. Rather than assuming only one hypothesis is correct, dreams likely serve a variety of purposes. Knowing that so much is left uncertain about why we dream, we can feel free to view our own dreams in the light that resonates best with us. Ever wonder what your personality type means?

Behav Brain Sci. Sleep is also believed to be adaptive, having evolved to tune out the external world when the threat of danger is at a minimum. This explains why some animals sleep at night, others sleep during the day, and others sleep according to their own peculiar cycles. Only a few animals, such as frogs, exhibit states that cannot technically be considered sleep. Fun fact: Dolphins have uni-hemispherical sleep patterns, meaning that their individual cerebral hemispheres take turns sleeping!
Sleep is also extremely important for facilitating learning. Sleep strengthens neural connections, which are at the basis of learning. Studies have shown that in memory testing, participants perform better having slept in between tests than those who did not.
Other studies have shown that during exam weeks, students experience an increased amount of REM sleep, supporting the idea that when a greater amount of mental consolidation is necessary, sleep, especially REM sleep, is vital to the brain and body.
