Lucid Dreaming

1.1 WHAT IS LUCID DREAMING?

Lucid dreaming means dreaming while knowing that you are dreaming. The term was coined by Frederik van Eeden who used the word "lucid" in the sense of mental clarity. Lucidity usually begins in the midst of a dream when the dreamer realizes that the experience is not occurring in physical reality, but is a dream. Often this realization is triggered by the dreamer noticing some impossible or unlikely occurrence in the dream, such as flying or meeting the deceased. Sometimes people become lucid without noticing any particular clue in the dream; they just suddenly realize they are in a dream. A minority of lucid dreams (according to the research of LaBerge and colleagues, about 10 percent) are the result of returning to REM (dreaming) sleep directly from an awakening with unbroken reflective consciousness.

The basic definition of lucid dreaming requires nothing more than becoming aware that you are dreaming. However, the quality of lucidity can vary greatly. When lucidity is at a high level, you are aware that everything experienced in the dream is occurring in your mind, that there is no real danger, and that you are asleep in bed and will awaken shortly. With low-level lucidity you may be aware to a certain extent that you are dreaming, perhaps enough to fly or alter what you are doing, but not enough to realize that the people are dream representations, or that you can suffer no physical damage, or that you are actually in bed.

1.2 IS LUCID DREAMING THE SAME AS DREAM CONTROL?

Lucidity is not synonymous with dream control. It is possible to be lucid and have little control over dream content, and conversely, to have a great deal of control without being explicitly aware that you are dreaming. However, becoming lucid in a dream is likely to increase the extent to which you can deliberately influence the course of events. Once lucid, dreamers usually choose to do something permitted only by the extraordinary freedom of the dream state, such as flying.

You always have the choice of how much control you want to exert. For example, you could continue with whatever you were doing when you became lucid, with the added knowledge that you are dreaming. Or you could try to change everything-the dream scene, yourself, other dream characters. It is not always possible to perform "magic" in dreams, like changing one object into another or transforming scenes. A dreamer's ability to succeed at this seems to depend a lot on the dreamer's confidence. As Henry Ford said, "Believe you can, believe you can't; either way, you're right." On the other hand, it appears there are some constraints on dream control that may be independent of belief. See "Testing the Limits of Dream Control: The Light and Mirror Experiment" for more on this.

1.3 HOW ARE LUCID DREAMS RELATED TO OUT-OF-BODY EXPERIENCES (OBEs)?

A mysterious and highly controversial phenomenon sometimes occurs in which people experience the compelling sensation that they have somehow "left their bodies." The "out-of-body experience" or "OBE", as this fascinating phenomenon is usually termed, takes a variety of forms. In the most typical, you are lying in bed, apparently awake, when suddenly you experience a range of primarily somatic sensations, often including vibrations, heaviness, and paralysis. Then you experience the vivid sensation of separating from your "physical body" in what feels like a second body, often floating above the bed.

It is important to note the distinction between the phenomenal reality of the OBE and the various interpretations of the experience. What is really happening when you feel yourself "leaving your body"? According to one school of thought, what is actually happening is just what it feels like: you are moving in a second body out of and away from your physical body-in physical space. But this "explanation" doesn't hold up very well under examination. After all, the body we ordinarily feel ourselves to be (or if you like, to inhabit) is a phenomenal or mental body rather than a physical body. The space we see around us is not physical space as "common sense" tells us, but as modern psychology makes clear, a phenomenal or mental space. In general, our consciousness is a mental model of the world.

OBE enthusiasts promote lucid dreaming as a "stepping stone" to the OBE. Conversely, many lucid dreamers have had the experience of feeling themselves "leave the body" at the onset of a lucid dream. From a laboratory study, we have concluded that OBEs can occur in the same physiological state as lucid dreams. Wake-initiated lucid dreams (WILDs) were three times more likely to be labeled "OBEs" than dream initiated lucid dreams. If you believe yourself to have been awake, then you are more likely to take the experience at face value and believe yourself to have literally left your physical body in some sort of mental or "astral" body floating around in the "real" physical world. If, on the other hand, you think of the experience as a dream, then you are likely to identify the OBE body as a dream body image and the environment of the experience as a dream world. The validity of the latter interpretation is supported by observations and research on these phenomena.
