SEEING WITH THE EYES CLOSED
Looking with closed eyes must be a similar sensation to the one babies have in the womb. Babies can distinguish light and shade (and sound) through the mother's body and they turn in the direction of the light. It is also similar to animals who have a second eye-lid which when dozing, which allows them to detect changes in light and shade.
Normally, when looking with closed eyes, we see little stars, or vague shapes, and streaks of light, or sometimes a kaleidoscope image. This is a result of our normal habitual focused vision. When looking in a panoramic way with the eyes closed, we can see light all around, as though it shines out and in through the forehead, temples, and cheeks.
To some extent this must be an optical illusion ... but animals who have their eyes on both sides of their heads, would have had this optical illusion through millions of years of dozing. So now, stretch your empathy and imagine how it might be for a duck or a horse to see light in and through their entire heads.
Looking with two eyesA letter from Michael Heinbockel :
I found a way to fall asleep very quick. I don‘t know why but it almost always works.
I close my eyes and focus on the back of my lids. That totally stops me from thinking and having pictures in front of my inner eye.
It reminds me of your idea to look at a wall without focusing.
First i noticed my eyes felt warm, then a far stronger sensation, i noticed how i'd got two eyes – rather than one vision point or field which i was looking at.
>Two eyes, yeah, same experience here.
... and then the abstract thoughts started and i thought ... if it works, it's something to do with the two brain halves not being connected and coordinated by the one field or object of vision.
i did a google search for
"birds eye open controls brain awake"
Obviously it's common knowledge: birds can sleep with one eye open and half of their brain awake, and they control how awake they are, by how open their eye is.
I don't use this regularly. I have done it a couple of times and it quickly blanks out the thinking, like a vacuum. Maybe this "looking with two eyes closed " is associated with trance states.
