All Amazing Facts About Your Dreams that You Might Not Know


Dreams are Mysterious, bewildering, eye-opening, and sometimes a nightmarish hell. Your dream’s length can vary from a few seconds to as long as 30 minutes. The average person goes through 3-5 dreams a night, mainly occurring in the rapid eye movement (REM) stage of sleep; it’s in this stage where the brain is at its most active, almost as if you were awake.

Below are 20 Interesting Facts About Dreams that You Might Not Know:

  1. You Forget 90% of your Dreams

Many people keep a dream diary by the bedside table to help them record their dreams, and with good reason. Within 5 minutes of waking, half of your dream is already gone; within 10, you will have forgotten 90% of it. Freud theorized that dreams are forgotten because they contain repressed feelings or thoughts we don’t want to remember. Dream researcher L. Strumpell, on the other hand, blames the vagueness of dreams; because we tend to remember things by association and repetition, remembering dreams can be quite challenging.

  1. Women have More Nightmares than Men

In a 2009 study conducted by Jennie Parker, British researcher, and psychologist for the University of the West of England, it was discovered that “women, in general, do experience more nightmares than men.” Women’s nightmares were also reported to be more emotionally intense than men’s. The test involved 100 women and 93 men between the ages of 18 and 25, who were asked to record their dreams in diaries.

  1. Night Owls Have More Nightmares

A study conducted by the Yúzúncú Yil University in Turkey has shown that those who stay up and wake up late have a higher chance of belonging to the 2-6% population who has weekly nightmares. The study states that, although cortisol levels rise in the morning, irregular sleep patterns disturb circadian rhythms and lead to the stress hormone affecting dreams.

  1. Your Dream Might be the Next Big Thing

According to Harvard University psychologist Deirdre Barrett, several game-changing ideas came about from dreams. In a weeklong study conducted on college students, Barrett asked the students to incubate answers to school assignments and other problems they were facing at the moment. The study concluded that 50% of the volunteers dream about their problem, and 25% dream of a solution.

  1. Dreams Can Help You Lose Weight

For those looking to lose some extra pounds, you’ll be glad to know that dreams do burn calories. In a study conducted at St. Luke’s Hospital in New York, volunteers went under a strict diet regimen for four days under various sleep conditions. They were then asked to fast on day five and were allowed to eat as much as they liked on days 6 and 7. The results showed that those who slept longer and had more dreams each night were less hungry, specifically for fat- and carbohydrate-rich foods. On the other hand, volunteers who slept only 4 hours each night found that their metabolism slowed down, and they ate more on the 6th and 7th day.

  1. Depressed People Have Better Dreams

In a study that involved 23 women and 26 men going through a divorce, psychologist Rosalind Cartwright from Rush University found that those diagnosed with clinical depression were better off than their more resilient counterparts. While the depressed subjects had shorter, more pleasurable dreams, their better-adjusted peers had more ruthless dreams, usually involving their exes.

  1. Nightmares Help Pregnant Women

Researchers at the University of Messina in Italy found that pregnant women who had bad dreams about birthing traumas or losing the baby often experienced shorter labor periods.

  1. Violent Dreams Can be Warning Signs

If you think nightmares are bad, then imagine having a rare sleep disorder wherein you act out violent dreams by kicking and screaming. According to a study published online on 28 July 2010 in Neurology, this can be an early sign of brain disorders as you get older.

  1. Dreams are Stress-Busters

In a study published in the Nov. 23, 2011, issue of Current Biology, UC Berkeley scientists found that the brain showed decreased levels of chemicals associated with stress during REM sleep. According to Matthew Walker, associate professor of psychology and neuroscience, previous emotional experiences lose much of their negative effects the next day because they have been reprocessed in a neuro-chemically safe environment during the dream state.

  1. People Tend to Dream about the Same Things

A 2004 study, which was conducted by scientists from the Sleep Laboratory at the Central Institute of Mental Health in Mannheim, Germany, showed that most of the 55 typical dream themes occurred at least once in most of the participants’ lifetimes.

  1. Sexual Dreams are a Common Occurrence for Everyone

Psychologist Antonio Zadra, in a study conducted in 2007, was able to show that dreams about sex account for approximately 8% of all reported dreams for both men and women. The most common type of sexual dream involved intercourse, while some dreams involved kissing and fantasies.

  1. Not all Dreams are Colourful

While many people dream in color, it’s estimated that one person in 8 has dreams in black and white. Dundee University’s Eva Murzyn suggests that “…there could be a critical period in our childhood when watching films has a big impact on the way dreams are formed.” She concluded this from the fact that dreams during the 20th century were almost always devoid of color; the shift to colored dreams occurred only during the 1960s, coinciding with the advent of Technicolor.

  1. Dreams Paralyze You

During REM or dream-phase sleep, your body suppresses the release of neurotransmitters such as norepinephrine, serotonin, and histamine—all vital in stimulating motor neurons. This effectively paralyzes the body and puts it in a state of REM atonia, a condition wherein the muscles are in a state of relaxation that borders on paralysis.

  1. Our Pets Dream Too

Studies have shown that REM sleep and its associated brain states also occur in a number of animals.

  1. There is a Science to Dreams

While dream interpretation focuses on understanding dream meaning and deciphering their symbolisms, Oneirology, the scientific study of dreams, is more concerned with the mechanisms and processes involved in dreaming.

  1. Blind People also Have Dreams

Not all dreams are visual, and this makes it possible for blind people to dream. Researchers from the University of Copenhagen and Glostrup Hospital in Denmark published a study in Sleep Medicine stating that blind people’s dreams mostly involve auditory and gustatory sensations. While people who become blind after birth have visual dreams, those who were born blind also have vivid dreams, thanks to a broader array of sensory inputs.

  1. Dreams are More Vivid for Quitters

According to the Journal of Abnormal Psychology, 33% of 293 smokers who were abstinent for between 1 and 4 weeks reported having at least one dream about smoking, with these dreams being described as more vivid than usual. It was concluded that they were the result of tobacco withdrawal because 97% of the test subjects did not have them while smoking. The dreams were also rated to be as common as most major tobacco withdrawal symptoms.

  1. Déjà vu is a Thing

If you’ve ever had the feeling that you’ve already seen or felt something that you’re only experiencing for the first time, you’re not alone. A survey found that 18-38% of people who participated in the survey have had at least one precognitive dream, and 70% have experienced déjà vu. It’s also interesting to note that up to 98% of these people believe in the possibility of precognitive dreams.

  1. Familiarity Breeds Dreams

You may not be familiar with all the characters in your dreams, so it might surprise you to know that those strangers in your dreams are actually people you have already seen. Throughout your life, you have already seen thousands of faces that you may not necessarily remember. The mind does not invent faces for the people in your dreams; it already has an ample supply stored somewhere in your memory.

  1. Dreams Can Melt into Reality

Sometimes, you may dream of frolicking in a meadow and then suddenly hear the shrill sound of bells, only to wake up to the sound of your alarm clock. This phenomenon is known as Sensory Incorporation, wherein elements of your physical surroundings incorporate and merge with your dream. A study conducted by Nielsen in 1993 has shown that the physical sensation of pressure on the participants’ legs was incorporated into their dreams, subtly yet directly.


  1. The fact that dreams can have physiological effects, such as influencing weight loss and metabolism, is surprising. This could open up new avenues for using sleep and dreaming patterns as part of holistic health and wellness regimes. The interplay between sleep, dreams, and physical health is worth deeper investigation.

  2. The finding that blind individuals have non-visual dreams underscores the adaptability of the human brain. It is compelling to think about how sensory inputs other than vision can create such vivid dream experiences. This might have implications for how sensory information is integrated and processed in the brain.

  3. The statistic that 90% of dreams are forgotten within minutes post-waking is fascinating. Freud and Strumpell’s differing theories on this phenomenon highlight the complexity of dream recall. Continued research in this area could uncover more about how we process and store memories.

  4. The correlation between REM sleep and stress reduction aligns well with current neurochemical theories. Also, the potential for dreams to inspire problem-solving, as suggested by the Harvard study, merits further exploration. This could potentially lead to novel educational and cognitive strategies.

  5. The breadth of this article’s content about dreams opens up new avenues for understanding the subconscious mind. The differentiation in dream patterns between genders and the implications of sleep patterns on nightmares are particularly intriguing. These insights could have profound implications for both neuroscience and psychology.
