During the day time, we are conscious of our surroundings and the brain does its work.

During sleep, we are not conscious. We have dreams. But the brain continues to function. After we awake though, there is only a memory of the dream experience. Is it possible to observe our dreams - that is, can we observe dreams as they occur and be conscious that we are dreaming?

    $\begingroup$ I am also interested if there is some work in neuroscience or cognitive psy in exploration of lucid dreams. $\endgroup$

    $\begingroup$ As user1406647 mentions, the topic of Lucid Dreaming is related. $\endgroup$

Lucid dreaming is a practice in buddhism. La Berge (1980) describes in some detail how he learned to dream lucidly, and several authors managed to induce lucid dreams in their test subjects through electrostimulation, food supplements and other means. There are some popular books that claim to teach the skill, some of them written by La Berge.

    $\begingroup$ it might be worth noting that it is also a current subject of research. for example I found this very recent article (july 2016) that did a meta-analysis on reported prevalences of lucid dreaming. they conclude that about 55% of the general population experienced one or more lucid dream in their life $\endgroup$

  • $\begingroup$ Thank you, @awakenting. This is the article, in case the link dies: Saunders, D. T., Roe, C. A., Smith, G., & Clegg, H. (2016). Lucid dreaming incidence: A quality effects meta-analysis of 50 years of research. Consciousness and Cognition, 43, 197-215. $\endgroup$

During REM sleep (during which dreams seem to occur), we experience muscular atonia – our muscle can’t move. When the region responsible for muscular atonia is impaired, patients seem to live through their dreams. It has been studied in cats by Michel Jouvet.

I believe that this shows that it is reasonable to trust our subjective experience here : we are conscious of the dream while we have it – although, when we recall it later, it’s probably very much reconstructed. The relation between temporality and consicousness will remain a very tricky question, and it may actually be impossible to differentiate "being conscious as it occurs" and "having a memory of the dream experience". You can find an extensive discussion on the relation between temporality and consciousness in Daniel Dennett’s book Consciousness explained , chapter 6 - Time and Experience. (And there is probably more in his more recent book, Sweet dreams but I haven’t read it).


My answer to the question is yes. I have personally experimented (not voluntarily) conscious dreams a few years ago.To be more precise, I was conscious in dreams but also conscious to dream.

Of course this answer is a testimony, not a scientific proof, of the existence of conscious dream.
But maybe in cognitive science, many serious testimonies constitute a proof.

Let me add an interesting remark and a question:

As I said, the processes of consciousness and dream seem to coexist, but as water and oil, they tend to separate quickly:

In my experiments, when the process of consciousness started in a dream, then the dream becomes increasingly blurred and awakening occurs rapidly.
I remember to have consciously walked and explored my dreams worlds for a few minutes or quarter of an hour (to be more precise, it seemed to have had this time), but not more ...

Is there a cognitive explanation for this quick separation ?

To make a nod to the Indian philosophy (@SaiKrishna):
Consciousness is light and dream is shadow.
When the light encounters the shadow, the shadow disappears...

  • $\begingroup$ so when you say you were conscious in your dream, where you aware that you are in a dream and tried to get out and perhaps woke up? $\endgroup$

    $\begingroup$ @gfdsal: I did not try to get out, I wanted to stay in it consciously for few hours (because it was new and funny), but I only succeed to stay few minutes, because (as I wrote above) consciousness leads to awakening. $\endgroup$ Jan 25, 2021 at 16:08

Yes we can. The state is nowadays called 'Lucid Dreaming' and it is not a theory or New Age superstition. It has been scientifically proven first by Dr Keith Hearn and consequently by Dr Stephen Laberge. They both used variations of the same method, namely having the dreamer produce prearranged, measurable signals from inside the dream once the become lucid.

Additional Subjective Info:

Really for something like that you can try it for yourself. With a bit of discipline everyone can do it. I am exploring it myself and from the people I have told through the years five followed the methods and they were all succesful. I recommend the book 'Are you Dreaming?' by Daniel Love as it is scientific and extensive, covering all levels. If you ask me, every scientist that deals with the mind should be developing this skill. It is the ultimate introspection playground (and lots of fun).

One word of caution. If you google the term you are going to end up with billions of New Age and religious cults and wild theories about aliens, gnomes, angels, other dimensions etc.

Unless you are interested in the sociology of belief and cult formation just ignore the lot and read the science and the 'Are you Dreaming?' book (no I am not getting any money from the author).

  • $\begingroup$ @StevenJeuris yes but the right one is really short and points to a search on Amazon for books which is a bad way to find good info for this subject. Also the first phrase puts unnecessary emphasis on the Buddhist take on the subject. $\endgroup$
