The following is an excerpt from the MRI Technician School Blog. Great stuff. Read the full article here.
Late-night snacks can cause nightmares: Nightmares in adults are much less common than in children, but there are some factors that can trigger scary dreams. Besides stress, medications and depression, late night munchies can interfere with your body’s metabolism. Eating late will make your brain feel like it needs to stay active for your body, which can lead to crazy dreams if you fall asleep instead of use up your energy.
Dreams occur all the time, not just during REM sleep: Doctors and scientists used to believe that dreams could only occur when people were in their deepest cycles of sleep, or REM sleep. In fact, dreams can occur at any time, though dreams you have during NREM sleep are usually less intense and less vivid. The National Sleep Research Project proposes that “it’s possible there may not be a single moment of our sleep when we are actually dreamless.”
Day dreams are real: The psychology department at UC Santa Cruz explains that our bodies and brains don’t necessarily require actual sleep to dream. As long as certain forces are in effect and the environment is right — when we tune out external stimuli but our brains are still active, for example — we have the potential to dream.
Smells affect your dreams: A 2008 German study found that positive and negative smells affect dreams: positive smells result in positive dreams while negative or unpleasant smells result in bad dreams.
Blind people don’t “see” in their dreams: For people who can see, it can be hard to imagine dreaming without lifelike imagery. But blind people dream, too, though not in the same way. According to The Accidental Mind, people who were born blind or who became blind at a very young age generally experience dreams according to their other senses.
