- I'm kind of curious as to what you're talking about here. During REM
- sleep (when most dreams occur), there is an active inhibition of your
- motor neurons, but I don't know of any special "disconnection of
- gravity sensors". Do you?
-
- Like I said, I don't know if there has been any research on the topic. My
- data comes strictly from my own experience in the hypnagogic state and
- dream remberences on awakening. Since I rarely awake in the middle of a
- sound sleep (during some phase of which REM would presumably occur) my data
- is based on a kind of mental activity that sleep investigators might have a
- name for other than dreams.
-
- Nonetheless, whenever I awake I can almost always remember the most recent
- flash or two of the mental activity that I call dreams. Over the years
- I've developed a pretty good idea of some of the properties common to these
- dreams, and some of the more interesting include:
-
- A sense of "down" in the direction of my feet rather than in the
- direction of the center of the earth.
-
- A pronounced absence of gravitational sensation, such as:
- . the sense of effort in maintaining the kind of posture the
- dream depicted or
- . the pressure of the real bed or dream ground pressing itself
- against my body
-
- To my (decidedly unscientific) mind this says "gravity disconnect" in
- rather pronounced terms, and I'll be very surprised if the idea doesn't
- show up in the scientific literature sooner or later.

-
- But actually, the point isn't worth debating. I was trying to explain my
- assumption that my dream feet are in the same direction as my real feet,
- which on reflection is a point that stands on it's own (so to speak).

-
- Again, not a presupposition, rather the result of a rather large body of
- personal experience. To reproduce my experience, I would suggest paying
- close attention to things like orientation when making the hypnogogic
- transition between sleep and wakefulness (and back).
-
- Perhaps I'm a totally unique specimen, but I doubt it. When lying down
- thinking about doing things in the real world I visualize myself erect with
- respect to the earth, and at 90 degrees with respect to my current
- reclining position. Indeed it's my appreciation of the effort involved in
- getting up and actually performing the imagined act that drives home the
- fact that I am indeed awake and lying down.
-
- When I slip into dreamland, I still imagine myself erect with respect to
- the dream ground, but gone is the sense of effort that connects me to my
- reclining body. If I pay close attention (as much as can be expected in a
- hypnogogic state) I notice that the dream world is at a ninety degree angle
- with respect to the real world.
-
- This shifting of "world" orientation suggests to me that my dream self is
- sharing body awareness with my sleeping self, since I don't get a sense of
- my body changing orientation in the transition, just the environment.
-
- In any event, this line of exploration is dangerously close to being
- philosophical, and probably doesn't belong in this forum. I'm merely
- responding to the charge of "nonsense", and defending my implication that
- this would be a good area for sleep researchers to look into.
