Dreams
 

 

Our dreams combine verbal, visual and emotional stimuli into a sometimes broken, nonsensical but often entertaining story line. We can sometimes even solve problems in our sleep. Or can we? Many experts disagree on exactly what the purpose of our dreams might be. Are they strictly random brain impulses, or are our brains actually working through issues from our daily life while we sleep -- as a sort of coping mechanism? Should we even bother to interpret our dreams? Many say yes, that we have a great deal to learn from our dreams.

 

  • Why Do we Dream?

 

For centuries, we've tried to figure out just why our brains play these nightly shows for us. Early civilizations thought dream worlds were real, physical worlds that they could enter only from their dream state. Researchers continue to toss around many theories about dreaming. Those theories essentially fall into two categories:

  • Dreaming and the Brain:

When we sleep, we go through five sleep stages. The first stage is a very light sleep from which it is easy to wake up. The second stage moves into a slightly deeper sleep, and stages three and four represent our deepest sleep. Our brain activity throughout these stages is gradually slowing down so that by deep sleep, we experience nothing but delta brain waves -- the slowest brain waves .About 90 minutes after we go to sleep and after the fourth sleep stage, we begin REM sleep.
Rapid eye movement (REM) was discovered in 1953 by University of Chicago researchers Eugene Aserinsky, a graduate student in physiology, and Nathaniel Kleitman, Ph.D., chair of physiology. REM sleep is primarily characterized by movements of the eyes and is the fifth stage of sleep.

·        Dream Recall:

It is said that five minutes after the end of a dream, we have forgotten 50 percent of the dream's content. Ten minutes later, we've forgotten 90 percent of its content. Why is that? We don't forget our daily actions that quickly. The fact that they are so hard to remember makes their importance seem less.

 

 

·        How To improve your Dream Recall:

There are many resources both on the Web and in print that will give you tips on how to improve your recall of dreams. Those who believe we have a lot to learn about ourselves from our dreams are big proponents of dream journals. Here are some steps you can take to increase your dream recall:

  1. When you go to bed, tell yourself you will remember your dreams. (Author's note: In researching this article, I found that thinking about dreams before I fell asleep actually made me remember having them, so this step did work in my experience.)
  2. Set your alarm to go off every hour and half so you'll wake up around the times that you leave REM sleep -- when you're most likely to remember your dreams. (Or, drink a lot of water before you go to bed to ensure you have to wake up at least once in the middle of the night!)
  3. Keep a pad and pencil next to your bed.
  4. Try to wake up slowly to remain within the "mood" of your last dream.

·        Controlling Dreams “Dream Incubation.”

Dream incubation is learning to plant a seed for a specific dream topic to occur. For example, you might go to bed repeating to yourself that you'll dream about a presentation you have coming up or a vacation you just took. Those who believe in problem solving through dreams use this technique to direct their dreams to the specific topic.
While somewhat similar to lucid dreaming in that problems can be solved, dream incubation is simply focusing attention on a specific issue when going to sleep. Several studies have shown this method to be successful over a period of time. For example, in a study at Harvard Medical School, Dr. Diedre Barrett had her students focus on a problem before going to sleep and found that it was certainly possible to come up with novel solutions in dreams that are both personally satisfying and reasonable to an outside observer. In her studies, two-thirds of participants had dreams that addressed their chosen problem, while one-third actually came up with solutions in their dreams.

·        Dream Facts:

  • Most dreams last anywhere from five to 20 minutes.
  • People don't only dream in black and white, as was once believed.
  • Even though they may not remember them, everyone dreams several times a night. In fact, during a typical lifetime, we spend about six years dreaming.
  • People who have been blind from birth have dreams that are formed from their other senses (e.g., touch, smell, sound).
  • When people are snoring, they're not dreaming.
  • Elephants (and some other animals) sleep standing up during non-REM sleep, but lie down for REM sleep.
