Compelling Theories About the Dreaming Brain
Inactive regions in the brain can help dreamers understand why they do not wake up even when they know they have an odd dream. The areas that are responsible for putting things into perspective remain dark while dreaming. Shutterstock

3. While certain parts of the brain have an increased frequency during dreaming, there are also passive brain areas. 

Like how scientists studied which parts of the brain are active while someone is dreaming, they have also completed an analysis of the dormant areas. The areas of our minds that are responsible for placing items in a physical context remain dark. This discovery helps to explain why sometimes proportions are often distorted in dreams. One example of this is within the right inferior parietal cortex’s inactivity. The lack of activity in this area may explain why we can experience dreams in both the first and third person. The inferior parietal cortex is not the only area of the brain that remains dormant.

Executive regions of the prefrontal cortex responsible for reality testing and self-monitoring also remain dark. That can explain why the dreamer is completely unfazed when a person is replaced with an animal while you are in a work meeting. When we are awake, a situation like that will make zero sense. However, since that part of the brain remains inactive or dormant while dreaming, we are entirely unfazed by it.

2. As many of us know, sleep is critical to our overall health. Adequate sleep can contribute to the frequency and type of dreaming you may experience. 

How can we ensure we are getting enough sleep and experiencing a dream state? The good news is that there are several simple ways you can enhance your sleep and achieve that dream state. The first change you can to make sure your room is dark and that you are not looking at bright light sources within the last hour or two before going to bed. It is talking to everyone who scrolls social media before going to sleep. You can also purchase some dimming lights to stimulate sleepiness.

The second thing you can do is to create a consistent schedule by going to bed and waking up at roughly the same time every day. That helps to signal to your body that there is a regular time for sleeping. To get sufficient sleep, you should keep the temperature in your house cool at night. Your body temperature naturally drops at night for sleep, and a lower room temperature signals that it’s time for rest.

If you have trouble falling asleep or wake up in the night feeling restless, it’s vital that you don’t stay in bed awake. Doing so trains your body that your bed is not a place for sleeping. Try getting up and reading a book and when you start to feel sleepy again, return to bed. Lastly, avoid caffeine late in the day or too much alcohol. Both interfere with quality sleep and will either keep you awake or stimulate frequent wakeups throughout the night.

You may find yourself dreaming about people or situations you experienced the day before, or perhaps they are people and situations from a week ago. Shutterstock

1. Dream lag occurs when the images, experiences, or people in your dreams are ones that you have seen recently. 

When you see someone recently, perhaps the previous day or a week before, and then see them in your dream, this action is a dream lag. Experts asked people a simple question: did they see images before? In turn, they report that most images came from the previous week. The idea is that certain types of experiences can take a week to become encoded into your long-term memory. Some of the images from the consolidation process will then appear in a dream. Events people experience while awake is said to feature in one to two percent of dream reports.

On the other hand, 65 percent of dream reports reflect aspects of recent waking-life experiences. Memory theorists suggest that the hippocampus in your brain takes those events, whether from the previous day or the last week, and selects some of them to transfer into long-term memory. Those chosen then begin to transfer over to the neocortex for permanent storage. The transfer process can take about a week. Therefore, dreaming participates in the relocation of memory storage from the hippocampus to the neocortex over time. In short, you can see encoded images stay in your long-term memory by merely paying attention to your dreams!
