Everyone has a theory about their dreams and the science or meaning behind them. And when the weather hots up, the more bizarre they tend to get. “Dreams are a fascinating and enigmatic phenomenon that occur during sleep, encompassing a vast realm of imaginative experiences,” says sleep expert and CEO of MattressNextDay, Martin Seeley. “They are a collection of thoughts, images, sensations, and emotions that unfold within the theatre of our minds.” Why do we dream? When we sleep, our brain enters a complex state where it engages in various cognitive processes, explains Seeley, including memory consolidation, problem-solving and emotional regulation. “Dreams are thought to emerge from these processes, weaving together fragments of memories, desires, fears, and subconscious thoughts into a narrative or non-linear sequence,” adds Seeley. “And they can be surreal, vivid, or mundane, blurring the boundaries between reality and fantasy.” While the precise purpose and meaning of dreams remains a subject of exploration and debate, Seeley says they can serve as a portal into the inner workings of our minds: “Providing a canvas for exploration, processing of emotions, and glimpses into the subconscious depths of our psyche.” Why do we dream more when it’s hot? Lisa Artis, deputy CEO of The Sleep Charity, says: “When the weather is hot, it can disrupt our sleeping patterns, making it difficult to fall asleep in the first place – and causes us to wake more often during the REM (rapid eye movement) sleep phase.” REM sleep is where we experience intense dreaming, explains Artis – so waking during or at the end of this cycle can mean we are more likely to remember our dreams. “Dreams happen regularly, but are often forgotten and our mind’s way of unpacking the day’s events, dealing with stress and sorting through our day-to-day thoughts,” notes Artis. Our body heat generally peaks in the afternoon then starts to drop over an evening to prepare us for sleep, says Artis. Melatonin, the sleep hormone, is produced when this happens.“An ideal temperature is around 16-18°C and anything around the 24°C mark can cause restlessness,” says Artis. “So, it’s no surprise that when we’re experiencing a heatwave with temperatures reaching over 30°C, it affects our sleep.”Can a heatwave really make dreams more surreal? The connection between heatwaves and the content or nature of dreams is not fully understood. However, there may be a few possible explanations if your dreams seem weirder when the weather heats up – although Seeley points out these are all speculative. First off, he agrees it may have a lot to do with the fact we’re less comfortable and waking more when it’s hot. “These frequent awakenings can interrupt the normal sleep cycle and result in a higher probability of remembering dreams, including the more unusual or vivid ones,” he notes. “So, during a heatwave, the increased frequency of waking up during the night might contribute to a greater recall of strange or funky dreams.” Secondly, the body’s physiological response to heat may influence brain activity, he adds: “Heat can affect neurotransmitter levels, such as serotonin and dopamine, which play a role in regulating mood and emotions. These alterations in neurotransmitter activity might impact the content and emotional tone of dreams, potentially leading to more surreal or bizarre experiences.” Psychological factors could also play a role. Heatwaves can cause restlessness and increased stress levels in some individuals. Seeley adds: “Stress and emotional fluctuations can manifest in dreams as strange or unusual scenarios, as the mind processes and attempts to make sense of these experiences.” Can we stop strange heatwave dreams happening? While it’s probably not possible to completely control the content of our dreams, there are certain strategies you can try to promote better sleep – and potentially reduce the likelihood of experiencing a restless night and unusual dreams during hot weather. Create a cool sleep environment: “Use fans, air conditioning, or open windows to circulate cool air in your bedroom – and consider using lightweight, breathable bedding materials,” says Seeley. Stay hydrated: “Drink enough water throughout the day to prevent dehydration, especially during hot weather,” he continues. “Being adequately hydrated can help maintain a balanced sleep cycle.” Practice relaxation techniques: “Engage in activities that promote relaxation before bed, such as deep breathing exercises, meditation, or taking a warm bath,” suggests Seeley. “These practices can help calm your mind and promote a more restful sleep.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live What are the royals doing to mark the anniversary of the Queen’s death All the times Kate has channelled the late Queen’s style since her death YouTube begins verifying videos by UK doctors to tackle health misinformation

Grimes appeared to take to X/Twitter where she begged Elon Musk to let her see her three-year-old son. The 35-year-old musician had responded to a tweet by Musk biographer Walter Isaacson, according to the screenshots. It comes following the release of his Time magazine article about the billionaire on Tuesday where photos featured of Musk alongside Neuralink executive Shivon Zilis and their twins. An image of Musk with X was also included in the story. In her response, Grimes tweeted: “Tell Shivon to unblock me and tell Elon to let me see my son or plz respond to my lawyer,” the tweet reads, according to the screenshot. “I have never even been allowed to see a photo of these children until this moment, despite the situation utterly ripping my family apart.” Grimes and Musk split in September 2021 and share two children together - three-year-old son X born in May 2020 and a one-year-old daughter Exa Dark Sideræl otherwise known as Y, born in December 2021, via surrogate. The twins Musk shares with Zilis were born a month before Y in November 2021. It's not the first time the Oblivion singer has taken to Twitter before deleting tweets, as she recently shared how she had experienced "the single most traumatic events of my life.” "A lot has been going on in my life for the last few years that I have mostly kept from the public,” she added. “I may still do that out of respect for others, but the last few days rly taught me that without fundamental change I’m gna die from stress and my kids won’t be ok.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Kanye 'Ye' West and rumoured wife Bianca Censori have turned heads with risqué outfit choices while roaming Italy. Censori, who previously worked for West's Yeezy brand, was spotted covering her ensemble with a hotel pillow after furious locals hit back at the "offensive" choices in recent weeks. The shots show Censori in a sheer, nude bra and leggings with a purple pillow covering her chest. West sported an all-black outfit with no shoes. The photos shared to X/Twitter were soon met with confusion from fellow users, with one writing: "How completely ridiculous these people are. Put on some clothes and then you won’t have to take a hotel room cushion out sightseeing with you - and you even get your arms free! Novel concept." Another asked: "Why is Bianca walking around naked with a pillow?" Meanwhile, a third added: "Kanye & Bianca Censori are unhinged. Someone ought to stage an intervention. Wearing a pillow? Him walking in socks?" The pair have not been shy of controversy while travelling Italy after photos captured the rapper exposing his bare bottom at the back of a boat in Venice. The images prompted the boat company to issue a ban for life, adding they were "completely unaware" West had dropped his pants, as they were focusing on water traffic. A source for the Venice Police told the Daily Mail : "There are standards of public decorum that have to be followed by tourists and locals alike and any breaches are severely punished. The images of West with his trousers down while in a taxi as he and his partner crossed the lagoon were seen all over the globe."

Scientists in Israel have created a model of a human embryo from stem cells, without using sperm, eggs or a womb. A team at Israel's Weizmann Institute of Science made the model, which resembles an embryo at day 14, when it acquires internal structures but before it lays down the foundations for body organs, and the work was published in the journal Nature. But the scientists involved said it would take a long time yet to create an embryo from scratch. Team leader Jacob Hanna said the team took stem cells derived from adult human skin cells, as well as others cultured in the lab, then reverted the cells to an early state.They then manipulated them to make a model of an embryo, rather than an actual or synthetic one. "The question is, when does an embryo model become considered an embryo? When that happens, we know the regulations. At the moment we are really, really far off from that point," Hanna said. However, they said the work could open the door to new ways to test the effect of drugs on pregnancies, better understand miscarriages and genetic diseases, and maybe grow transplant tissues and organs. "They are not identical. There are differences from human embryos, but still, this is the first time, if you open an atlas or a textbook, you can say - yeah I can really see the similarity between them," said Hanna. "In about 1 percent of the aggregates we can see that the cells start differentiating correctly, migrating and sorting themselves into the correct structure, and the farthest we could get is day 14 in human embryo development," he said. Their next goal, Hanna said, is to advance to day 21 and also reach a threshold of a 50 per cent success rate. Magdalena Żernicka-Goetz, a professor of development and stem cells at the University of Cambridge, said the study joins six other similar human embryo-like models published from teams around the world this year, including from her lab. "None of these models fully recapitulate natural human development but each adds to ways in which many aspects of human development can now be studied experimentally," she said.
