  • Hello Jacks and Sallys, Julian here for DNews. In the comments of a recent video Luke Hutton

  • asked us why we get nightmares. Well Luke today’s the day youve been dreaming about.

  • Or had nightmares about, if you don’t like my jokes.

  • Yes the common knowledge holds true that nightmares are often a reflection of your waking mental state.

  • Stressing about a looming unpleasantness, as well as anxiety from events passed can

  • cause nightmares. Really traumatic events like car accidents or wars can lead to nightmares

  • with recurring themes, or reliving the event over and over. Healing from the trauma should

  • cause the nightmares to become less frequent and intense over time. If youre among the

  • 5% of people who have nightmares often enough to affect your waking hours, consider seeing a therapist.

  • Working through stress or trauma in real life will help you sleep peacefully.

  • Nightmares can also be caused by medications or drugs, especially ones that affect neurotransmitters

  • like antidepressants or narcotics. People who have what psychologists define asthin

  • boundaries of the mindare more prone to nightmares too. These people tend to be more

  • creative and imaginative, and sometimes have trouble separating fantasy from reality. There

  • are also idiopathic nightmares, meaning we don’t know why they happen, they just do.

  • So if you have a nightmare every now and again, it’s nothing to worry about. 85% of adults

  • report having nightmares on occasion. Theyre more common for children, particularly young

  • girls, and are likely caused when the child is struggling to cope with normal childhood fears.

  • To understand nightmares, and to a larger extent dreams, it helps to know what’s happening

  • in your thinking meat while youre unconscious. Dreams and nightmares happen during REM,

  • the last step in the sleep cycle before it starts over. During REM your brain becomes much more

  • active than when youre in deep sleep. Your amygdala in your temporal cortex starts humming

  • along during REM, and that little guy is responsible for processing memory, decisions, and emotional reactions.

  • Some areas have even more activity than when youre awake, like the hippocampus,

  • which is the storage center of memory and emotions; and parts of your cortex, particularly

  • your temporal and occipital lobes. These regions handle sensory input and visual information, respectively.

  • There’s also some spikes in some fast wavelengths, likely caused by the

  • cortex communicating with the thalamus, which is thought to be a hub for information sharing.

  • One area of your brain that doesn’t light up in REM though is the prefrontal cortex,

  • which is used in information integration and episodic memory.

  • With all that brain talk I just threw at you in mind, the why and how of nightmares and

  • dreams starts to make a little more sense. The parts of your brain that are involved

  • in long term memory, emotion, vision, and language are all hard at work, but the prefrontal

  • cortex is literally asleep at the metaphorical wheel, meaning nothing’s really guiding

  • what the rest of your brain is doing. The result is bizarre dreams or nightmares, especially

  • when something has had a strong emotional impact. And since the REM stage gets longer

  • with each cycle and is the one you have right before you wake up, dreams or nightmares get

  • longer and more intense until finally you come out of it going, “What on earth was that about?”

  • So nightmares can be caused by stress or emotions, but do you have the ability to control them

  • while you sleep? Anthony has the answer here.

  • This question was asked by a viewer and we hope we answered it to his satisfaction. If

  • you have questions, lay it on us. You can ask them in the comments or on twitter or

  • facebook. Don’t forget to subscribe, it’s kind of important to come back so you can

  • see the answer, and I’ll see you next time on DNews!
