The benefits of lucid dreaming

Lucid dreaming: the ability to control or influence your dream environment

Every night, most of us dream, but about 20% of people experience lucid dreaming at least once a month. In these rare moments, dreamers are aware they're dreaming, and can even control their actions. Though linked to increased frontal lobe activity, why this state occurs remains a mystery.

Researchers believe the brain consolidates memories, processes emotions, and plans for the future during dream states

Several brain regions are involved in lucid dreaming

Some scientists propose that lucid dreaming may require the emergence of a brain network, which is when multiple brain regions collaborate to perform certain functions. Research shows that lucid dreaming is associated with increased activity in the frontal lobes—associated with decision-making, voluntary movement, attention management, and more.

Scientists are learning to guide your dreams using sound and touch

Researchers are using a technique called "targeted dream incubation"—where stimuli like sounds or vibrations are introduced as you drift off—to influence dream content and potentially improve creativity, memory consolidation, and PTSD treatment. With the same mechanism, companies could theoretically target sleeping consumers with brand suggestions while they're unaware and neurologically susceptible, or assist in reducing nightmares.

Terminal lucidity is the phenomenon of sudden, heightened mental clarity when on the verge of death

The "Let's Talk Near Death" podcast explores phenomena around the end of life, inviting guests to recount their own experiences. This episode focuses on the phenomenon known as "terminal lucidity," where patients experience clarity, vivid memory recall, and more, typically following a heart attack, stroke, or other trauma.

The dreaming brain, as understood by scientists

Technology has advanced to where the seemingly separate fields of psychology and neuroscience are asking the same questions about dreams, such as whether they're more closely related to perception or visualization. Some field-intersecting findings include research that shows people with impaired face perception don't dream of faces, those with brain legion-related cognition difficulties deal with similar issues in dreams, and children's dreams change in parallel to their cognitive development.

Why 'spacing out' or dissociating may help reduce trauma awareness

Dissociation may have developed as a defense mechanism in the brain to help navigate intense emotional or physical situations by providing out-of-body experiences that put distance between the mind and the environment. However, in about 1.1% and 1.5% percent of the general population, a severe form of this separation can produce alternate identities, or alters.

There are psychological benefits to believing in spirits

A number of psychologists believe religion helps subdue our fears of death by giving us a sense of what’s to come and, therefore, a sense of control over how to ensure the best possible outcome.

How dreams affect your memory

In 1999, scientists conducted a study in which participants were asked to recall images flashed before them for milliseconds. They found that participants who slept before recalling the information performed better than those who had been asked to recall the same information that same day. This was some of the earliest convincing evidence of how crucial sleep is for learning and memory, findings that current research continues to strengthen.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

Journaling can improve mental wellbeing and promote positive interactions

Described as having therapy with someone who knows you well, documenting one's thoughts and feelings aids in information processing and can reveal personal issues. Methods include bullet journaling and gratitude, which a 2024 study linked to a longer lifespan.

Studies of psychedelic use may help shed light on the nature of consciousness

The nature of consciousness—what it is, where it comes from, and how it manifests as moment-to-moment experience—remains under debate by scientists. Recent studies show psychedelics were found to boost low-frequency brain signals known as delta waves, a behavior also seen during dream states.

The hippocampus plays a central role in dreaming

It's theorized that the hippocampus—a brain structure involved with memory formation and the simulation of imagined and novel scenarios using those memories—plays a major role in dreaming. Studies of people with damaged hippocampi show that they still dream, but their dreams lack the richness of detail described by others.

NDEs typically change people's outlooks drastically and can prompt depression

The phenomena are regularly categorized as hallucinations, but some specialists are interested in their psychological nuances. Many survivors report feeling less anxiety about death, though some surveys show the experiences can increase physiological sensitivities.

The benefits of extreme pain rituals, explained

We naturally avoid pain and see it as a negative experience. But many traditional cultures incorporate extremely painful rituals into their religious ceremonies, claiming they, in fact, provide ample benefits. Researchers were able to observe boosts in happiness and a sense of belonging in a tribe of Mauritians after they undertook a rigorously painful religious ritual. Read about the study here.

An overview of modern clinical research on LSD

Researchers have determined that LSD, taken in a medical setting, decreases anxiety related to "life-threatening disease," reduces brain reactivity to fearful faces, increases the meaning and emotional response derived from music, and more. No complications of LSD administration have been observed in medical settings, though acute adverse effects, including exhaustion, nausea, and difficulty concentrating.

Dreams have long been used for religious and political power

Classic literature and mythology attests to the crucial role dreams play in narratives, from the Virgin Birth to the prophetic visions of Gilgamesh and Enkidu. The heightened state of dreaming and its analog, hallucinating, have long held special power over the collective imagination.

People learned to fly in VR, and their brains then accepted wings as body parts

After 25 people used virtual reality headsets to practice flying with virtual wings—flapping their arms—their visual cortex responded to the wings almost as if they were real arms, treating them as body parts. The brain research has potential implications for how VR training may help people adapt to prostheses. (Free with email.)

PTSD is a long-lasting mental disorder linked to past traumatic events

Posttraumatic stress disorder is a mental health condition arising from traumatic events with four key symptoms: intrusive memories, avoidance behavior, negative moods and thoughts, and changes in emotional and physical reactions.

The benefits of power napping

Research shows it may not be beneficial to fight that mid-afternoon drowsiness: Power naps can make you more alert, reduce stress, and improve your cognitive function.

After 25 people used virtual reality headsets to practice flying with virtual wings—flapping their arms—their visual cortex responded to the wings almost as if they were real arms, treating them as body parts.

Why might someone want to stay in psychosis?

Author Abigail Gosselin writes that her verbal auditory hallucination, often assumed by others to be harmful or threatening in nature, offered a salve to loneliness, even as it told her to kill herself. This perceived benefit and others Gosselin shares offer insight into why people in psychosis may struggle to adhere to treatment and medication plans.

Ghost stories can help us process death

Scholar Coya Paz’s research into ghost stories indicated that people often use them to grieve and remember tragic histories. Paz notes that specters in stories almost always demand to be acknowledged. She also shares the three most common types of ghosts we hear about are either vengeful, unwelcoming, or comforting.

Nightmares are unpredictable, but are linked to stress, anxiety, trauma, and more

Nightmare comes from the terms "night" and "mare," an Old English word for evil, suffocating spirits. Nightmares are parasomnias, meaning they are undesirable events experienced during sleep, and may stem from building tensions in one's unconscious.

Sleep training, which can range from implementing a nighttime routine to letting your baby cry it out, is controversial, but does it work? While dozens of studies have found sleep interventions to be effective, it appears that many of these studies...

How to build curiosity

Change and uncertainty induce stress, but reframing the unknown into an opportunity for discovery has tangible benefits. Approaching change with curiosity enhances activity in the hippocampus and promotes neuroplasticity, promoting learning and serving as a barrier against anxiety. A neuroscientist explains how embracing the unknown, trying small experiments, and other techniques build curiosity.
