Each sleep position can influence your dreams — for better or worse — and your overall sleep. On your side. Sleeping laterally is the most common sleep position. Studies have found that right-side sleepers experienced more positive dreams and fewer nightmares than left-side sleepers.
The results of the study found that nightmares were more frequent for those who slept on their left side. For the subjects who slept on their right side, they reported dreams with the feeling of relief and safety. They also had better quality sleep than those who slept on their left.
According to scientific research conducted by Van Winkle, people who sleep on their left side are far more at risk of having nightmares, whilst those who sleep on their right have a better quality of sleep due to 'feeling safer'.
The most popular way to sleep is favored by more than 4 out of 10 people, especially among women, who are twice as likely as men to sleep curled up on their side. For the most part, it's a healthy way to doze, because it allows your spine to rest in its natural alignment.
On your back: Sleeping on your back is the most common position for lucid dreaming, as it allows your body to relax fully and prevents you from rolling over during the night.
In most cases, said Dr. Krakow, a nightmare is mild, and in that situation, it's best not to wake the person who is having the nightmare. For example, if the person is simply tossing and turning, looking concerned and/or whispering to himself, leave him be. But nightmares vary in intensity.
In a lucid dream your senses are heightened. Sight, sound, smell, taste, and touch are all more extreme than what you would experience in real life. Emotional feelings may also be intensified. You'll feel a greater sense of happiness and pleasure from engaging in enjoyable activities.
The worst sleep position: On your stomach
“This position puts the most pressure on your spine's muscles and joints because it flattens the natural curve of your spine,” he says. “Sleeping on your stomach also forces you to turn your neck, which can cause neck and upper back pain.”
Research shows that a side-sleeping position improves the brain's glymphatic system, which is the cleansing system that removes waste from the brain. This waste is believed to contribute to the development of Alzheimer's disease and other neurodegenerative diseases.
There's some evidence that sleeping on your left side may shift your heart and disrupt your heart's electrical current. Also, many people with heart failure report having trouble breathing in this position. Sleeping on your back can worsen sleep apnea and snoring.
You feel scared, anxious, angry, sad or disgusted as a result of your dream. You feel sweaty or have a pounding heartbeat while in bed. You can think clearly upon awakening and can recall details of your dream. Your dream causes distress that keeps you from falling back to sleep easily.
Although some continue to believe nightmares reduce psychological tensions by letting the brain act out its fears, recent research suggests that nocturnal torments are more likely to increase anxiety in waking life.
Nightmares can arise for a number of reasons—stress, anxiety, irregular sleep, medications, mental health disorders—but perhaps the most studied cause is post-traumatic stress disorder (PTSD).
Common causes include stress, negative life events, the experience of trauma as in posttraumatic stress disorder (PTSD), depression, other psychiatric disorders, and medication side effects. This topic reviews the causes, differential diagnosis, evaluation, and management of nightmares in adults.
Nightmares are associated with disturbed sleep, low well-being and affect daytime mood and behavior. Nightmare disorder is a very common comorbidity in nearly all psychiatric conditions. In borderline personality disorder (BPD), for example, up to 50% are troubled by frequent nightmares [5-7].
Sleeping on your back is associated with self-confidence. Back sleepers may also be stubborn and have high expectations for themselves and other people. Depending on whether you sleep with your arms down at your sides (reserved) or arms and legs outstretched (relaxed, open-minded) might also have an influence.
A 2019 study published in Journal of Alzheimer's Disease, showed among 165 participants (45 with diagnosed neurodegenerative disease, 120 controls) a supine sleep position (on back, head at body level) for more than 2 hours per night increased the risk of dementia by almost four times (3.7 times greater).

Avoid sleeping with your arms higher than your shoulders (for example, by putting them under your pillow). It constricts your nerves and your veins. Your arms can be numb, and the weight is heavy on your shoulders, which makes getting up harder. Finally, sleeping on your back is technically the best way to sleep.
Side sleeping helps prevent the airway from collapsing and can reduce snoring. "And so, all in all, sleeping on the side — perhaps with their head slightly elevated as long as that's comfortable — is a good way to sleep," says Dr. Krahn. Side sleeping also is recommended during pregnancy, especially the last trimester.
Sleeping without a pillow can help some people who sleep on their stomach, but it is not a good idea for everyone. People who sleep on their side or back will usually find that sleeping without a pillow puts pressure on their neck. By doing this, it can ruin a person's quality of sleep and lead to neck and back pain.
While research is limited, anecdotal reports show that sleeping without a pillow can help reduce neck and back pain for some sleepers. Stomach sleepers are generally best suited for going pillowless, because the lower angle of the neck encourages better spinal alignment in this position.
Although some theorists have suggested that pain sensations cannot be part of the dreaming world, research has shown that pain sensations occur in about 1% of the dreams in healthy persons and in about 30% of patients with acute, severe pain.
Sometimes the dreams we have seem so real. Most of the emotions, sensations, and images we feel and visualize are those that we can say we have seen or experienced in real life. This is because the same parts of the brain that are active when we are awake are also active when we are in certain stages of our sleep.
Lucid dreams are when you know that you're dreaming while you're asleep. You're aware that the events flashing through your brain aren't really happening. But the dream feels vivid and real. You may even be able to control how the action unfolds, as if you're directing a movie in your sleep.
