Healing in your sleep: Do lucid dreams provide therapeutic benefits?
Have you ever experienced a lucid dream? Those surreal moments when, during sleep, you suddenly realize you are dreaming? Maybe you've even taken control, bending the dream world to your will. What if these experiences could offer more than just a nighttime thrill? Could they actually be therapeutic?
A recent study led by Çağatay Demirel of the Donders Center for Cognitive Neuroimaging at Radboud University Medical Center has shed light on the
brain mechanisms
behind
lucid dreaming
. The study published in
JNeurosci paper
sheds light on the brain activity during wakefulness, rapid-eye-movement sleep, and lucid dreaming.

Lucid dreaming happens when you are conscious during a dream. This happens during rapid eye movement (REM) sleep, the dream stage of sleep.
This means you're aware that you're dreaming while you're still in the dream. In short, it is a form of metacognition, or awareness of your awareness. In some cases, lucid dreaming also lets you control what happens in your dream. While many experience lucid dreams very vividly, others feel it like a haze. In the 1970s, Stanford psychophysiologist Stephen LaBerge proposed the concept of lucid dreaming, but many were skeptical. However, psychologists slowly started studying, conducting research, and tapping into the lucid dreaming capacity of patients for therapeutic purposes. About
55 percent
of people have experienced at least one or more lucid dream in their lifetime.
Lucid dreaming is a surreal phenomenon, and the researchers examined data from multiple labs and included what the authors say is the largest sample size yet used in the field. By comparing brain activity during lucid dreams, regular REM sleep, and wakefulness, the researchers found unique patterns in how the brain functions during this conscious dreaming, and how brain regions communicate may be linked to changes in perception, memory processing,
self-awareness
, and cognitive control. The shifts in brain regions linked to self-awareness, perception, memory, and cognitive control are also factors that are closely associated with emotional regulation and mental health. This has sparked interest in whether lucid dreaming can be used as a tool in therapy.
'This research opens the door to a deeper understanding of lucid dreaming as an intricate state of consciousness by pointing to the possibility that conscious experience can arise from within sleep itself. This work offers a perspective that could challenge the traditional binary view of sleep and wakefulness in future research,' Demirel, who led the research, said.
'Taken together, these findings illuminate the electrophysiological correlates of LD, laying the groundwork for decoding the mechanisms of this intriguing state of consciousness,' the authors concluded.

New COVID variant NB.1.8.1 found in the UK: What are the symptoms?
So, just when we thought we were done hearing about new COVID variants, another one popped up. This time it's called NB.1.8.1, and yes, it's already made its way to the UK. It's raising some eyebrows among doctors and scientists because it spreads quickly and might sneak past some of our usual defenses, like past infections or vaccines. But before we panic, let's break it down: what this variant is, how it might feel if you catch it, and what you can do to protect yourself. So, what exactly is NB.1.8.1? NB.1.8.1 is a subvariant of Omicron, the version of COVID we've all become a bit too familiar with over the last couple of years. It showed up in early 2025 and, since then, has been spotted in over 20 countries—including the US, several places in Europe, and now the UK. The World Health Organization (WHO) is keeping a close eye on it and has labeled it a 'variant under monitoring.' That basically means it's not time to panic, but it's definitely worth watching because it spreads quickly and might be better at dodging the protection we get from vaccines or past infections. What are the symptoms of NB.1.8.1? The symptoms so far look pretty similar to previous Omicron variants, but there may be a few slight differences from person to person. Here's what people are commonly reporting: Fever and chills – One of the first signs that something's off. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Trade Bitcoin & Ethereum – No Wallet Needed! IC Markets Start Now Undo Dry, persistent cough – Not fun, and can stick around for a while. Fatigue – That 'I can't get off the couch' kind of tired. Sore throat – Scratchy, painful, or just uncomfortable. Runny or stuffy nose – Feels like a bad cold. Headaches – These can range from mild to pretty intense. Muscle or body aches – General body pain or soreness. Loss of taste or smell – Still showing up, though less common than with earlier strains. Not everyone gets all of these, and some people might only have mild symptoms—or none at all. It's also totally possible to think it's just a regular cold or allergies. Who's at higher risk? So far, most cases seem to be mild, especially for people who are vaccinated or have had COVID before. But, as always, there are groups who need to be more cautious: Older adults (especially those 65+) People with weakened immune systems (due to illness or medications) Unvaccinated folks, particularly those who haven't had any booster shots If you or someone you know falls into one of these categories, it's a good idea to keep an extra eye on any symptoms and get medical help if things don't feel right. Any new or unusual symptoms? Besides the usual cold-like signs, a few people with NB.1.8.1 have mentioned some less common symptoms too: Upset stomach – Nausea, vomiting, or diarrhea Skin rashes – Not super common, but it's happened Dizziness or confusion – Rare, but reported in a few cases If something feels off—especially if you're in one of the higher-risk groups—it's better to get checked out sooner rather than later. How can you protect yourself? The usual COVID safety stuff still works here. Nothing fancy—just the basics: Stay up to date on your vaccines and boosters. They may not completely prevent infection, but they do help your body fight off the virus better. Wear a mask in crowded indoor places, especially if you're high-risk or around someone who is. Wash your hands regularly with soap and water (or use hand sanitizer if you're out and about). Keep some distance from people who are coughing or not feeling well. No need to be paranoid, but being smart helps. What to do if you feel sick If you start feeling symptoms that could be COVID—whether it's NB.1.8.1 or not—don't ignore them. Here's what to do: Self-isolate as soon as you can. Take a COVID test (rapid tests can help, but PCR is more accurate if you can get one). Let others know if you've been in close contact recently, just in case. Rest up and monitor symptoms—and definitely reach out to a healthcare provider if things get worse. NB.1.8.1 is yet another reminder that COVID hasn't totally disappeared. But it's also a sign of how far we've come—because now, we know what to look out for, how to handle it, and how to protect ourselves and each other. So, stay informed, stay calm, and take care of yourself. A little caution goes a long way, and you'll be better prepared if this variant (or the next one) comes your way.

Former Sena corporator booked for drunk driving and assaulting doctor in Thane
Thane: The Rabodi police have booked a former Shiv Sena corporator for allegedly driving under the influence of alcohol, dangerously ramming his car into another vehicle, and assaulting a doctor in a road rage incident near Castle Mill area on Tuesday evening. According to the complaint lodged by a 31-year-old doctor residing in Thane and working at a Bhiwandi civil hospital as an orthopaedic surgeon, the incident occurred around 6:50 pm. The doctor and his sister were returning home in their car after picking up a food parcel from Vikas Complex. As they approached the Meena Tai Thackeray Chowk, another car driven by Mahesh Wagh allegedly recklessly in the wrong lane collided with the doctor's vehicle. The police said that the doctor stated he slowed down his car to avoid the impact, but Wagh's car still struck the front-right side of his car. Even as he attempted to step out, the accused allegedly scraped the vehicle further while trying to drive off. When the doctor signalled the driver to stop, the man reportedly accelerated and hit the doctor's foot. The police, quoting the FIR, said that the doctor's sister also attempted to stop the accused by standing in front of Wagh's car, but he allegedly continued to drive forward, endangering her as well. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Trade Bitcoin & Ethereum – No Wallet Needed!
