Some incredible new research is paving the way to literally record and play back your dreams - and lucid dreams - just like movies.
Though the technology is in its infancy, the concept has already been proven by similar fMRI studies. Now, scientists at the ATR Computational Neuroscience Laboratories in Kyoto have applied this system to dreamers' brains, marking the first step on the way to recording and replaying our dreams.
The Japanese study published in the the journal Science, called Neural Decoding of Visual Imagery During Sleep, reveals how scientists used a Functional Magnetic Resonance Imaging (fMRI) machine to scan the brains of three volunteers as they started to enter the dreamstate.
"We focused on dream experience which can be detected just a few minutes after the sleep onset," explained researcher Yukiyasu Kamitani.
The researchers then woke the volunteers more than 200 times to ask them what they were dreaming about. As annoying as that may sound, their dream descriptions meant that specific dream imagery could be linked with specific patterns of brain activity.
That's because dream stimulus - just like waking stimulus - creates certain patterns of blood flow in specific areas of the brain. And it's highly consistent. So, if you raise your right arm in your dream, the same parts of the brain activate as when you raise your right arm while awake. This happens across a range of stimuli, whether you're listening to classical music or recalling a nasty smell.
The result? A primitive yet fully functional dream decoder, translating raw brain activity data into moving images representative of dreams. With increasingly more data, the translation will become increasingly more accurate and vivid.
The following video is a demonstration of this emerging technology. The images are a computer's interpretation of what the volunteer was dreaming about.
Now, here's the dreamer's description of what was really happening:
"What I was just looking at was some kind of characters. There was something like a writing paper for composing an essay, and I was looking at the characters from the essay or whatever it was..."
"In this field of dream decoding no-one has managed to successfully do this before," commented neuroscientist Jack Gallant. "If you could build the perfect dream decoder it would create a movie on your television screen and it would just replay your dreams."
While it may be a few more years until we can all play back our dreams in that fashion, the latest study is a landmark event that could one day see us directing blockbusters from our beds...
These days, fMRI research is all the rage when it comes to understanding the brain. A similar study last year led to this extraordinary reconstruction of visual imagery.
Scientists at UC Berkeley built up an extensive library of YouTube clips and trained their software to translate brain scan data into movies. The major difference was they were comparing fMRI scans with volunteers watching Hollywood movies (as opposed to dreaming). While they're both pursuing similar goals, the latest Japanese research is the first attempt to use fMRI to actually record and play back our dreams.
Chloe is a natural lucid dreamer. That's to say that all of her dreams are conscious (lucid), highly realistic and incredibly vivid. She can remember these dreams as far back as being a toddler. That level of mindfulness we regular folk strive to achieve in our dreams is always present in her nightly escapades. Her dreams, by default, are highly intense, profound and acutely self aware.
Lucid dreams are a life-changing opportunity for all of us. If you want to learn how to have lucid dreams, this section gives a flavor of the mindset and the techniques you'll learn. I'll be absolutely up front with you. If you're going to learn how to have lucid dreams, you need to inject three things in your life starting today. Time: it takes time to learn a new skill like lucid dreaming. For instance, time to record your dreams each morning. Time to meditate and incubate a self-aware mindset. Time to perform a pre-sleep lucidity routine.
It's the most frustrating thing about lucid dreaming. You finally realize you're dreaming, get excited about the infinite possibilities... and immediately wake up. What's the point of all this lucid dream training if the experience only lasts a few seconds? How much more effort is it going to take to learn how to prolong your lucid dreams? The answer is: none at all.
Learning to have lucid dreams -- it's fun, intensive, frustrating, euphoric, bizarre, daunting -- yet ultimately, lucid dreaming is a hugely rewarding and life changing experience. Learning how to lucid dream is like any other skill that you develop over time. There is no magic secret. But there are a number of tried-and-tested methods that you can employ. Below I've listed a number of those techniques to get you started. Happy dreaming...
This week I was the recipient of a ten-year anniversary gift from Pete (meaning I opened a package with his name on it and was all "Hey cool! Is this for me?!"). The gift was a set of AcousticSheep SleepPhones - wireless headphones embedded in a plush headband which receives audio from your nearest device. The main reason he got this for me was to listen to music and podcasts more comfortably in bed. It's also a top selling product among joggers, air travelers, the partners of snorers, and insomniacs. AcousticSheep SleepPhones have applications in entertainment, leisure, sport and sleep therapy.
Experts agree that everyone is capable of having lucid dreams. Dreaming itself is a normal function of the mind. We all dream every night, even if we don't remember. And we all achieve conscious awareness while awake every single day. So what does it mean to combine these states? Why, the amazing ability to have conscious - or lucid - dreams. Sounds simple, doesn't it? So why do I keep hearing from people who say they can't achieve their first lucid dream?
