Mods not sure if this belongs here or not, please move if deemed appropriate.
I almost always spend part of the night sleeping in a recliner. Sometimes I have the strongest feeling of movement, like I was in a rocking chair or maybe as if the recliner itself were on an axle and rolling slowly toward my feet. Most of the perceived movement is toward my feet, although sometimes therre is a slow rocking back and fourth sensation. I find very convincing while it is occurring. During the event I am awake to reason out that I am in the chair and that the chair is not moving, so I do not think that it is an “edge of sleep thing”.
I reckon this is some sort of stimulus issue within the inner ear. Whenever it happens I have been sleeping laying down between 4 or 5 hours, I get up, use the restroom and lay in the recliner. So the I could see something along lines of your inner ear is used to the horizontal position and when I assume the more nearly upright position the nerves in the inner ear get confused."
So any Doper ever heard of this?
