Scientists Match Dream Images To Photos

Soulskill posted about 2 years ago | from the that's-nice-but-please-don't dept.

Science 47

scibri writes "Scientists have learned how to discover what you are dreaming about while you sleep. A team of Japanese researchers scanned the brains of three people as they slept, and compared the scans to those of the same people looking at photos of common objects. They were then able to tell, with 75% — 80% accuracy, if one of those images appeared in a dream."

They would be blurry and discolored anyway. I believe that pictures from the dreams are more suggestive than realistic. Like one of the photos I created a while ago: [] . Look how the plants are all recognizable, even if you can not see them directly. They are all just shapes in dirty water, but the brain thinks that they are real.

I did. Unfortunately, the whole "lucid dreaming" thing is overrun by people who think that they are shamans, crystal healers, and all sorts of other fools. It's less about "controlling your dreams" as it is "unlocking past life experiences" and other nonsense.

PrimaryConsult (1546585) | about 2 years ago | (#41711167)

That's why you learn from either a print book, or the simplest online guide out there, and ignore the discussion community entirely...

I know it is real because I have accidentally done it a few times, I just really don't care enough to improve the odds by doing all the mental exercises out there.

An easy example: A sign that you are dreaming is inconsistent numbers, and simply being aware of this fact will help trigger lucid dreams if you encounter numbers in a dream. To improve the chances of this occurring, you can make a habit of checking your watch / clocks / other things with numbers twice while awake, and verify that the numbers remain consistent. This isn't as easy as it sounds, which is why I gave up...

Inception, anyone?

Re:let me know when i can control my dreams (1)

riondluz (726831) | about 2 years ago | (#41721997)

Since you mentioned 'Inception' I thought I'd comment that I found and installed an app on my N900 called "realitycheck" []

The app is rather simple: its just a reminder app.
The mechanism is to look at your hand, then look away, then look at your hand again.

The idea behind it is that what one does a lot of when awake creeps into our dreams and you will dream about looking at your hand, 2x.

The reason this is important is that lucid dreaming is controlled by the right hemi of the brain; the visual, emotional side.
The left (logical) hemi tries to interpret what the right side is experiencing (emotional memories expressed in images).

When you look at your hand the second time in your dream, your hand will be deformed because the left hemi doesnt have time to process the info fast enough. So, like the top that never winds down, the dreamer knows, in their dream, that they are dreaming.
This is the point where they have the ability to control their dream.

Re:let me know when i can control my dreams (0)

Anonymous Coward | about 2 years ago | (#41712739)

Basically, you just want to get into the habit of checking for dream logic during your waking hours. I wouldn't say it's hard, just tedious in the same way that making your voice more feminine is tedious; all you have to do is follow the exercises and keep on it. The problem is not getting bored of counting your fingers or seeing if you fall after jumping.

Re:let me know when i can control my dreams (0)

Anonymous Coward | about 2 years ago | (#41714415)

Problem is I check my watch twice anyway because I forgot what it was the first time. If I could remember what time it was the first time I checked, my life would be a lot easier!

iMadeGhostzilla (1851560) | about 2 years ago | (#41715067)

Same thing with text: if you re-read it and it's different, it's a dream. Another one: jump, and if you come down slowly (like you're on Moon gravity), you know you're dreaming.

Last time I accidentally started lucid dreaming, I changed the angle of view and aspect ratio of my vision, which was really strange and really kind of cool at the same time. I've been interested in doing more lucid dreaming, but don't really care quite enough to train myself for it. I just enjoy it when it happens.

Re:let me know when i can control my dreams (0)

Anonymous Coward | about 2 years ago | (#41719795)

Some people do dream checks all the time so they train themselves to do it while dreaming. Feh. I find that doing it before bed is more than enough to remember to do it while dreaming, and makes me look like less of a weirdass.

Re:let me know when i can control my dreams (1)

chichilalescu (1647065) | about 2 years ago | (#41711849)

I went to the wikipedia page after reading the xkcd comic that had "lucid dreaming" in its mouseover text.
There, I saw that lucid dreaming is taught to people who have a lot of nightmares, while undergoing therapy, so that they can gain control over their dreams.
It sounded intriguing, but I didn't have the patience to learn more about it.

In any case, sorry to hear you ran into stupid people.
But if you did train yourself to do this, I do have a couple of questions:
(1) can you control the passage of time in your dreams in any way?
(2) how elevated is the math you can do without waking up?

Re:let me know when i can control my dreams (1)

Cunning (2693141) | about 2 years ago | (#41718385)

I lucid dream most of the time; generally something happens in the dream that doesn't seem right (internal inconsistencies), which alerts me to the fact that it's a dream, and from that point I can control pretty much anything I like, so long as I don't think too hard about it (which causes me to wake up). One thing I have difficulty with is other people's reactions in dreams; I'm not sure if that's because a different part of the brain handles that or what, but the current location, people, objects and laws of physics are easy to mess with. It's utterly amazing, but it does make conventional entertainment pretty dull. Watching some superhero fly around at the movies is extremely meh when you remember what it feels like to do it yourself! Luckily my subconscious isn't too adept at clever plot twists, so I can still enjoy well-written books and movies even if the action sequences are second hand.

Re:let me know when i can control my dreams (0)

Anonymous Coward | about 2 years ago | (#41711035)

Indeed, I did it myself a few year back. It takes a fair amount of effort and time when you're not sleeping, but the real effort comes from stopping yourself turning a lucid dream into an excuse to have sex with anyone you can imagine!

I've never been wrong when I've said: I can tell you're not dreaming about this picture I drew of the mobile drilling machine I piloted while trying to head off a subterranean nuke-missile and save the world, before I decided to take a detour and visit my "middle-earth" high-school, which is why the pic shows the Magma-Men and I gathered 'round the rig with glowing smiles.

Honestly, you could monitor my dreams and accurately compare every photograph of everything in the entire Universe and you'd still never find a match for what's going on in my head -- Unless, on the off chance you have a picture of a gorgeous nude demon girl with charcoal skin and lidless black eyes with her arm around me sitting on the basket ball bleachers while we watch a swarm of angelic and infernal beasts play a celestial game of hoops with my flaming immortal soul...

TeslaBoy (1593823) | about 2 years ago | (#41718733)

The title is really inaccurate. I was at this conference and talked to Kamitani about it. He was able to determine whether the dreams we have when entering sleep (not those we have in deep sleep) contained faces, places, or inanimate objects. Significantly above chance levels. It's good work, but it's nothing like reconstructing a photo of what someone was dreaming. Kamitani also tried to explicitly do this, but so far, it's not possible. The linked article makes all of this really clear.
