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.

So here's a quirky little nighttime oddity that can strike terror into your soul. Sleep paralysis. It's the mechanism that stops you from acting out your dreams. It happens to you every single time you go to sleep, and you've probably never even been aware of it. There's a lot to say about sleep paralysis. One the one hand, it's a very normal bodily process. One the other, it can be a terrifying sleep disorder. And on the third hand (yes, that's three hands now) it's the gateway to the lucid dream world. It covers quite the spectrum of emotions.
Want to get your hands on some futuristic technology? Then why not use your lucid dreams to explore new scientific concepts and developments? In fact, it's thought that numerous well-known scientists including Nikola Tesla exploited their dreams to simulate theories and prototypes in action. Here are five futuristic concepts to get your dream cogs in motion.
So you want a real challenge for your next lucid dream? Check out these thought experiments. They have no right or wrong answers, at least as far as we can prove in 2015. If you undertake any of these - please add a comment below. The beauty is that everyone's experience will be different and I'm eager to read your results.
So you want to know the easiest way to start lucid dreaming? You found it. I've been lucid dreaming since I was 14 years old. Over the years, I've researched a lot about lucid dream induction. I have practiced many different exercises and developed my own ways to become lucid and stay conscious in the dream state for longer. The following is a snapshot of all that work. It's my big picture take on lucid dreaming for beginners, whittled down into 5 sensible steps to prime your mind for lucid dreams.
Everyone knows that horror movies beget nightmares. But did you know that peak nightmare experiences are a common trigger of lucidity? It's like the terror of realizing you're about to be ripped to pieces by the knife monster shocks you into realizing you're dreaming. So next time you're writhing about in a nightmare scenario, or screaming at yourself to wake up, take a second to focus your energy on declaring the dream for what it is: a harmless rendering of your innermost thoughts and fears. Lucidity is then yours.
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?
