How you can control your dreams — an expert explains how lucid dreaming works


You may have heard of lucid dreaming, the type of dream where the dreamer is aware of dreaming. Is lucid dreaming a real phenomenon? Sleep expert Matthew Walker explains how much we know about lucid dreams so far. Following is a transcript of the video.

Jessica Orwig: What if we could control our dreams?

When most of us dream, our thoughts and actions are involuntary. The dream plays out as if we were watching a movie. But not all dreams are the same. There is another kind of dreaming called lucid dreaming, which is more like playing a video game than watching a movie.

Matthew Walker: By definition lucid dreaming is simply the act of knowing that you’re dreaming whilst you’re dreaming.

My name is Matthew Walker. I am a professor of neuroscience and psychology at the University of California Berkeley.

Most people actually think of lucid dreaming more in the sense of actually beginning to control what you’re dreaming. So, you gain volitional control and you decide what’s going to happen during your dream.

Orwig: Frequent lucid dreamers claim that they can control many parts of the dream such as teleporting themselves to another location, learning to improve real-life skills, or even eating fire. It might sound far-fetched. And until recently we lacked the technology to prove if lucid dreaming was real or not. But a series of recent studies has shed light on the phenomenon.

Walker: Scientists have designed experiments and they’ve been able to demonstrate objectively that when people say that they’re doing something in that dream that they actually are.

Orwig: In 2012, scientists reported results from one of the first experiments that objectively measured lucid dreams using fMRI scanners.  fMRIs measure the rate of blood flow to different areas of the brain, so they can relay information about a person’s thoughts and actions simply through a series of images.

For the study, scientists first asked participants to clench their fists while they were awake. This lit up key areas of the brain on the fMRI scanner. After that, participants were asked to fall asleep and dream about clenching their fists. Sure enough — similar regions of the brain lit up in both cases.

Lucid dreaming comes naturally to some, but many of us have never experienced the sensation. However, that doesn’t mean it’s impossible.

Walker: How can we actually become more capable of lucid dreaming? Well, it’s a little bit tricky, but you can certainly try to tell yourself that you will remember that you’re dreaming whilst you’re dreaming before you actually fall asleep. So, try to go through a mantra chant as it were. Some people actually try to do deliberative things whilst sleeping, like turning on the lights in a room. And that helps them to become aware that they are dreaming at the moment of dreaming itself and therefore they gain lucid control.

Orwig: Those who can already control their dreams with ease say lucid dreams aren’t only for entertainment but can also be used to expand one’s conscious boundaries.

On the other hand, lucid dreamers have also reported frightening accounts where they have trouble distinguishing reality from the dream. In some cases, this can be a sign of mental illness, and should be taken seriously.

But why do some people have the ability to lucid dream but not others? And what is happening in our subconscious that triggers the experience? There’s still a lot we have to learn about the causes and effects of lucid dreaming.

Walker: It seems to be only around 20 to 30% of the population are actually natural lucid dreamers. So, perhaps if it was so beneficial mother nature would have had all of us being table of lucid dreaming. And the fact that we’re not perhaps means that it’s not necessarily beneficial. But we actually don’t know. Maybe those 20 to 30% of people who do lucid dream are at the forefront of hominid evolution, and they are going to be the next species of preference. We just don’t know.

How Amazon solved people’s biggest fear about shopping in its cashierless stores (AMZN)


amazon go

  • Amazon Go, the retailers camera and sensor-filled cashierless store, opened on January 22.
  • The company says the store is "highly accurate" at being able to tell what you took off the shelf and charging you for it.
  • If the store does make a mistake, fixing it is easy.

Amazon has opened its new cashierless store, with no lines and no waiting.

Amazon Go’s convenience is easy to understand, but concerns still arise. How will the store charge me correctly? And if it gets it wrong, is it easy to fix?

As the store was in beta for the last year, open only to Amazon employees, the company has had plenty of time to fine-tune its array of sensors, cameras, and other technology to ensure that customers will be charged correctly for what they took off the shelf in the store.

Gianna Puerini, head of Amazon’s Go program, told the Seattle Times that the system is "highly accurate." If there’s a question, a greeter standing near the entrance might ask you to show a receipt, though that only happens a "small fraction of the time.

For those times the system does not get right, you might walk out and notice that the system charged you for something you didn’t take. Luckily, getting rid of the charge is as simple as swiping it away on the receipt in the app, according to Puerini.

Amazon Go’s accuracy was reportedly a factor in delaying its opening from a year ago. The store was a lengthy beta test open only to Amazon employees since it opened in late 2016. Amazon said it had such an enthusiastic response from employees, it didn’t need to open the beta to the public.

Since then, it used all kinds of methods to try and trick the system, including dressing three employees in identical bright yellow Pikachu costumes. The store successfully tracked all three of the dressed up characters, charging them accurately for what they took off the shelf.

Liam Neeson’s story about his first reaction to seeing Helen Mirren is amazing



You may not have known this about Liam Neeson and Helen Mirren, but they actually used to date. They even lived together for a few years, too.

Well, during Friday’s edition of The Graham Norton Show, they had a little reunion. And Neeson opened up about the time he and his friend and co-star Ciarán Hinds were first introduced to Mirren on the set of the 1981 film Excalibur.

"She walked from like 100 yards away dressed as Morgana le Fay, and Ciarán’s my oldest friend, and we both went: Fuck," says Neeson in the clip above. "So I was smitten. I think Ciarán was smitten too, but I was certainly smitten." Read more…
