maybe completely off base... but reading this thread reminds me of 'penetration' by ingo swann (read free here: _http://www.wanttoknow.info/ufos/penetration.ingo_swann.pdf )
there is a point in his book where he details a lake being sucked up into a weird like UFO object
EDIT: I took the time to type out an excerpt detailing what I mean:
"I couldn't see anything unusual at all, save for what appeared to be some gray fog forming up in the direction of the lake. I thought it was morning for coming up
This fog continued forming for about five minutes, and suddenly I saw what had "begun."
For in a moment's eye flicker the grey fog changed, first into luminous neon blue, and then into angry purple.
At that point, Axel and one of the twins put a firm hand on each of my shoulders, and it was a good thing they did.
A network of purple, red, and yellow lightening bolts shot in all crazy directions through the "cloud", and I would have jumped up if not held down.
And then, there it was. Somewhat transparent at first, but in the next second, as if fading-up (like the movie term) out of nowhere, there IT WAS! - solidly visible over the lake whose reflecting water I could now clearly see.
And IT was GETTING BIGGER!
I don't really know what I had expected, but I had assumed that what I would see, if anything, would be something like a flying saucer. No chance of a saucer here, baby. Because IT was triangular, and its top angle sort of inverted in pulses, so that overall it appeared to be diamond shaped.
At that moment in my astonishment, we could hear a "wind" coming, and it moved past us like a tangible magnetic field, rustling the pine trees around us so much that some cones and branches fell on us.
The two firm hands on my shoulders tightened, warning me not to move in the pure physical reaction.
At the same time, ruby-red laser-like beams began shooting out of the "thing", which incredibly was now growing even MORE in size - while still stationary in its original position over the lake.
One of the twins now TALKED softly, although the sound of his voice was like thunder to me.
"Shit! They're enveloping the area! They're going to spot us!"
I had no time to wonder about what he meant. Indeed, some of the laser-red beams had begun blasting pine trees! Of all things!
At the same time, the "thing" had now increased it's size to what may have been about ninety feet wide.
The whole of this so far had been accomplished in COMPLETE silence, and even the electric bolts had not "crackled."
The blasting of the trees, though, was now audible, while at the same time I could being to hear low-frequency pulsations.
"They're blasting deer or porcupines or something in the forest," Axel explained softly in a calm but tense stage whisper. "The beams sense biological body heat, and they're sure to hone in on us."
At that moment, the two hands tightened on my shoulder and I was dragged and practically thrown back down into the arroyo.
There a terrific "pop" where we had been, and some large branches of nearby pines cascaded down on us.
That was my last sight of the triangular thing, but in that last moment I could see the WATER OF THE LAKE SURGING UPWARD - like a waterfall going upward, as if being sucked into the "machine!""
