Have you ever dreamt that you could fly or lost all your teeth or were late for a big test?
A dream is a collection of stories or photos created by the brain during sleep. Some people often search for information about what the scenario seen in a dream means.
There are 5 phases of sleep.
Why do we dream?
Neuroscientists are not sure why humans dream.
The best theories are that dreams are a means of eliminating unnecessary information and memories while processing the important data. Many people feel more refreshed after having dreaming sleep.
Possible explanations by scientists include:
- Representing unconscious desires and wishes
- Interpreting random signals from the brain and body during sleep
- Consolidating and processing information gathered during the day
A dream can be very vivid and real, make you happy or sad.
Some scientists argue that dreams have nothing to do with real thoughts and emotions. According to some researchers, even a dream story is a reflection of a person's thoughts, feelings, fears, desires.
Almost every person has had a nightmare at least once in their life, which leaves an unpleasant feeling even after waking up. Researchers believe that this type of dream is usually seen by people when they are under stress, they are afraid, they have suffered emotional or physical trauma, they are sick.
It is quite possible that some medication will cause a nightmare, ie it will be a side effect of the drug.
You may have heard the phrase "put the story to sleep", yes, sometimes a story seen or heard before going to bed becomes the main scenario of a dream.
Why do we have trouble remembering our dreams?
Unlike our lives while awake, dreams are not “real” experiences but instead represent a processing phase. Therefore the mind probably doesn’t mark them as worth remembering.
Furthermore, we are most likely to remember the last dream we had just before waking up in the morning.
Studies of brain activity suggest that most people over the age of 10 years dream between 4 and 6 times each night, but some people rarely remember dreaming.
Dream is still one of the unexplained phenomena, because due to its nature it is impossible to conduct laboratory research, therefore, when talking about this topic, scientists rely only on theoretical opinions.
Fast facts on dreams:
- We may not remember dreaming, but everyone is thought to dream between 3 and 6 times per night
- It is thought that each dream lasts between 5 to 20 minutes.
- Around 95 percent of dreams are forgotten by the time a person gets out of bed.
- Dreaming can help you learn and develop long-term memories.
- Blind people dream more with other sensory components compared with sighted people.
