Inception's Dream Science: Fact or Fiction? (PHOTOS)

Posted: 08/04/10 08:00 AM ET

Christopher Nolan's film "Inception" has come in number one all three weekends since its release and looks likely to do so again this coming weekend. As a dream researcher, I'm pleased to hear everyone talking about dreams--what they are, what's possible with them. I'm being asked every day which of "Inception's" premises about dreams are true and which are there only in the service of its sci-fi plot. In this column I want to address each of these as fact or fiction:

Dream Control

It is possible to influence your dreams by a technique psychologists call "dream incubation." Break though dreams--where a writer dreams the plot of a novel or a scientist dreams a formula or someone just has a major insight about their personal life--these can happen spontaneously, but you greatly increase their probability by specific requests of your dreaming mind. I describe dream incubation in detail in "The Committee of Sleep", but the simple version is if you want to dream about a particular person, or topic or problem, you should think about the topic once you are in bed, and form an image of that topic--because dreams are so very visual--and let it be the last thing in your mind before falling asleep.

If you want, you can have an object or photo on your bedside table to look at which represents the topic. Equally important, don't jump out of bed when you wake up; almost half of dream content is lost if you get distracted. Lie there and if you don't recall a dream immediately, see if there's any particular thought or emotion or image you woke up with. Just focus on that and sometimes a whole dream will come flooding back that would be lost if you just jumped up. In a week-long study with college students incubating dreams about homework and other objective problems, half dreamed about the problem and a fourth solved them.

Technology will probably advance so that we can see much more detail of human dreams with noninvasive surface electrodes. We can already alter brain activity by pulsing magnetic input to targeted areas. So far this has been used only awake and only on areas for mood (to alleviate depression) and areas of motor activity (to halt motor seizures). It seems plausible we might be able to make someone's dream happier even with current technology, but it seems unlikely we'll ever match the level of specificity in "Inception."

If you want to read more dream researcher's reactions to "Inception," you can do so at The International Association for the Study of Dream's webpage on the film.

After much trial and error, I have achieved limited success in manipulating my dreams, but, more importantly, I think, is the way in which I can now be "awake" inside my dream and watch what is happening. The awareness that I am still "asleep" and yet fully aware that I am asleep and dreaming,fully aware of my dream is difficult to maintain. The default seems to be that as one becomes more aware of ones dream, one awakens more and more until full waking is achieved.This renders dreaming a very different experience than if one just let it happen and sought no control or extra awareness of the dream.This is not something I now do very often, I enjoy the apparently random aspect of non-consciously controlled dreaming (the sub-consciousness is still in control of all other dreams). I find dream-awareness useful when dealing with nightmares and other disturbing imagery, I seem to be much more able to observe and understand the self--messaging service that dreams can be used as. A good article, it reminded me of all the time I spent practising dream--awareness, and the interesting things I learned from that practice.

The movie was entertaining, well made, had good acting, but that's about it. It does not reveal some deep, dark hidden truths.

In a recent article about how the brain works, it was revealed that there is a symbiotic relationship between mitochondria trapped within the cell and the rest of the cell, one that is put back into balance during sleep. Apparently mitochondria produce ATP, which enables animals to metabolize oxygen and to develop much more energy than they would without it, and during sleep the ATP levels are brought back up, which is why we are able to get over being tired and can feel revitalized after sleep.

The ability to use ATP was developed long before animals developed complex brains, so what goes on in our brains during sleep is much more complex than just going into neutral and recharging our energy levels. A brain during sleep is not confined by the same sensory inputs that it is tied to when the body is awake, as a reflection of what we think about and see during sleep will confirm.

The catch with lucid dreaming, it all becomes rather 'meh' after a while and more interesting to let dreams go where they will, with the odd adjustment to stir the imagination. Dreams, the collation of past emotional and physiological states, with more recent conditions and the forethought required to achieve positive trends and outcomes. The minds need to be 'more' happy, than actually just happy, there is real difference, one does not need to be happy, in order to be more happy than their current state ie. less miserable.
Of course the desire to affect other people's dreams, that is a different matter all together, a mental minefield with consequences often well beyond what is expected.

Thanks for an interesting article on dreams. Definitely been on my mind since I've seen Inception.

I would be interested in knowing why I dream one person fairly occasionally, but in my dreams that person never speaks to me. They will acknowledge my presence, smile, touch my arm or hug me, but never speak. This is often more puzzling to me than any other thing that occurs in the dream.

If you do control your dreams then how will you learn from them. I often use my dreams as a defense. I get warnings about things to come, so I prepare.

Most nights I am not able to determine what the dream is before I fall asleep, but once I am dreaming, sometimes I realize I am dreaming and control people, objects, settings, etc. But the more I mess with the dream the closer I get to waking up. I am usually able to recall a few dreams every night in vivid detail. Sometimes they are as mundane as waiting 10 minutes in line at a bank, or sometimes I am fighting in WWII.

Besides from all the good stuff I have bad experiences when I sleep as well. Night terrors (which I never recall), sleep walking/sleep eating.

Growing up, doctors said I would grow out of this...but although I act like a child sometimes, I am now 33 years old.

Just a comment:

"Occasionally people have been successful at whispering to sleepers and having a bit of the content incorporated into dreams. Most attempts at this either wake the dreamer up or don't make it into the dream."

The dreamer either accepts or rejects any attempts to insert anything into their dreams, but for their OWN purposes. They have full control.
Same as hypnotism. The subject will either allow themselves to be hypnotized or will not, for
their OWN purposes.
If allowed, the suggestions during a session will either be accepted or rejected by the subject, again, for their OWN purposes.
No "violation" of the individual will be allowed by the individual unless the individual desires to
use all or part of any type 'insertion' in their dreams for their own purposes.

Good article. Good research going on here.
Much detailed info can be found on dreams if one Googles Jane Roberts.
Thanks for validating her and Seth.
