Most of us don’t remember our dreams. This can be changed

Scientists say that we all dream, but not all can remember these dreams. We explain why this is so and there are many reasons. We also advise what to do to remember dreams.

1. Dreams occur during the REM sleep phase
2. Scientists have proved that in the same phase we “actively forget” unnecessary things, and the brain classifies dreams this way
3. Other factors, including character traits and the feeling of stress, can also affect the remembering of dreams

Dreams occur at the deepest stage of sleep, or REM. It can occur multiple times a night. This phase of sleep is characterized by rapid eye movement, increased body movement, and faster breathing. And this is when dreams occur – our brainwave activity is closest to when we are awake. This stage usually begins about 90 minutes after falling asleep and can last up to an hour towards the end of sleep. According to scientists, although we usually do not remember dreams, everyone dreams, including most animals.

Why do we forget dreams?

There are many theories as to why some people remember dreams and others do not. Most likely, as sleep medicine expert Dr. Sujay Kansagra points out “Our inability to remember dreams may simply be caused by sorting information during sleep and discarding irrelevant ones”.

Since dreams occur as our brain processes information, eliminating unnecessary information, remembering dreams may depend on an individual’s ability to remember. In addition, the brain prevents us from waking up during some active sleep and “blocks it”.

Scientists from the SRI Research Institute in Menlo Park, California decided to study a group of neurons in the hippocampus, the part of the limbic system responsible mainly for memory. They produce the melanin concentration hormone (MCH), a molecule that helps regulate both sleep and appetite. These neurons are active during the REM phase. As shown by the sleep record in mice, MCH inhibits the hippocampus, which is responsible for learning and memory. Activation of the MCH hormone prevents the storage of sleep content in the hippocampus.

On the other hand, brain activity can also help you remember sleep. The area known as the temporal-parietal junction processes information and emotions. This place is also responsible for wakefulness during sleep, which in turn allows the brain to better code and remember dreams. People who remember dreams with ease have more activity in the temporo-parietal connection.

We don’t remember dreams – other reasons

The amount of sleep also affects the ability to remember dreams – if someone is still awake and going into REM sleep, they will probably not remember sleeping when they wake up.

Even personality traits can be an indicator of whether someone will be able to remember their dreams. Creative people who think a lot about the future and their plans and dreams remember dreams more often than pragmatic people focused on achieving goals.

Stress or past traumas are also responsible for the ability to remember dreams. Mourning people will experience realistic dreams of the departed person. People with post-traumatic stress disorder (PTSD) may have vivid nightmares that involve flashbacks or repetitions of the trauma, either directly or symbolically.

What to do to remember dreams?

There are two ways to remember a dream. The first is … telling yourself before going to sleep that you want to remember them. If this is the last thought before falling asleep, we’ll probably wake up with sleep in our mind.

It’s also a good idea to try to remember as much as possible after waking up. If we want to remember a dream, first try to remember as many details as possible, and then get out of bed and take your time looking at the phone screen.

It is also worth taking care of sleep hygiene. Remember not to eat right before going to bed. It is also worth giving up looking at screens – TV, computer, telephone. To improve the quality of sleep, the room in which we sleep should also be ventilated beforehand.

Scientists are still unsure what exactly causes dreams. However, it is important to monitor your sleep as some abnormalities may signal that you need to change your lifestyle or see your doctor.
