Doc:
First of all, I agree that we should find out for ourself rather than relying on somebody else's parameters, no matter who sets them.
I haven't experienced the aperture, but others besides Moen and Monroe have, or at least ways something similar. A guy named Tayesin at astralpulse.com spoke of having such an experience, and he hadn't read about Monroe's and Moen's experience.
P.M.H. Atwater spoke of an experince that perhaps speaks of the same thing, only in a different way. Below are her words (I inserted dots when I broke up her dialogue).
"Before my view there spun two objects I'll call cyclones for lack of a better word. One was big at the top, narrowing to a spout. The other was inverted directly below, being big on the bottom and coming up to a spout. They formed an hourglass shape, yet the two spouts did not meet in the middle. Instead, there radiated out from that spot a kind of light I hesitate to call light. I don't know what to call it. The English language doesn't have such a word. Its rays shot out in all directions. I was suspended near the middle as I gazed in awe at the immensity of what towered before me. Both cyclones were spinning at tremendous speeds. The cyclone on the top was spinning clockwise. The one on the bottom was spinning counter-clockwise. Inside the upper cone, I glanced a tiny grain of sand I recognized to be me - or the Phyllis I had once been. Superimposed over Phyllis and the life she was living was all her past and future lives. Everything was happening AT THE SAME TIME IN THE SAME SPACE!
I also recognized others around Phyllis and the same thing was happening to them. I saw multitudes of other people everywhere inside the cone and the same thing was happening to all of them. I felt like I was viewing all of life and I came to realize time and space do not exist at all. I saw no movements that raised or lowered, went backwards or forwards, no left or right. What I saw was only expansion and contraction. No one was greater or less than anyone else, but some people were expanded out and growing more, others were so contracted they seemed to shrink and wither.
As I searched for more clues to life, I noticed Phyllis was also in the cyclone on the bottom and in the exact same position as on the top, and everyone else was there too. The bottom cyclone was a mirror image of the upper one. They were reflections of each other. As above, so below. Fascinating as this was, my attention soon turned to the middle. That's where I wanted to go, into it and through it. I felt as if it were the doorway to God. At last I would discover the source of God Itself.
I was on my way there. It was then that I heard my son's sounds. Slowly I found myself being pulled back. I never heard any words, only the sound of his voice. There was something different about it. There was love in his voice. A different kind of love. It was not the love of a son for his mother. It was something new - at least for me. It was the sound of one human being loving another human being because he wanted to, not because he was expected to. It didn't even matter if the other person loved back. The only thing that mattered was Kelly giving love freely because Kelly wanted to. His love was open, without any expectations, restrictions or standards. It was unconditional love. Real love! I really didn't believe that special kind of love existed on the Earth-realm. I had heard of it before but had associated it with Divine or Saintly revelations. It was happening now and my son was giving it. Such a precious gift was worthy of being received.
I choose to return and live again. There were no angels, or anyone else egging me along. I made the conscious choice and when I did, the cyclones disappeared and my living room returned. I slipped back into my body, entering again through the top of the head. This time, my body did not respond. It felt cooler and strange. I panicked. Instantly I became a tiny cheerleader and game coach, scurrying up and down my frame shouting words like: hey team I'm back, wake up everyone, I'm back now, I'm sorry I did this to you. I won't do it again, I'm really back to stay this time, come on everyone, I'm back. The air sacs in the lungs were the hardest to activate. It took real effort to get the bellows to expand. With the first sweep of breath, my consciousness returned to my head area and my eyes opened.

The first lecture paid for the trip and told me why I was there. It was given by Dr. William Tiller, a physicist with Stanford University in California. His topic was THE ETERNAL NOW, and he illustrated his talk by having his graphs and drawings projected onto a huge stage screen. He described at length what he felt the greater reality to be, that what we really are is an energy mass and how that energy worked. The climax of his talk came when he spoke of The Eternal Now, what he felt it looked like and how it functioned.
It was his belief that ALL THINGS HAPPENED AT THE SAME TIME IN THE SAME SPACE. The drawing flashed on the screen was of two cyclones inverted over each other, and where the two spouts should have met, there radiated an immense light shooting out in all directions.
There's a lot more to life than I had ever realized and I erupted from my chair. He saw it too. He knew about the cyclones! I wasn't crazy after all! I wasn't mad! I didn't hallucinate! It was all real! I really saw it! What happened to me was valid! I was sane! The learning continues."
