Please don't take offense at this article, but it is a bit more detailed.

That explanation is just fear of there really being other things in this universe talking! Unless it's happened to you and it has happened to me it's hard to fathom that other beings, can paralyze you in bed. I have met quite a few people, and one was taken by them, out of his body...they are interested in your soul, some of them not your body. There are lots of different galaxies out there and beings that have been around since the beginning of time. Our government knows and covered it up because they felt, we the people, could not handle it. Well they are real and that's why people are seeing more UFO's now. Soon in the next few years there presence will be made known again when we can handle it. You are lucky it hasn't happened to you!

Yeah, I don't know about this quiz, seems a bit flaky. I scored 79, I'm not sure what to make of that. The sleep paralysis seems more plausable, as I did have a legitimate fear of abduction. But I always have, as long as I can remember, believed in the existance of aliens, the idea that they were coming for me. I somehow felt targeted for one reason or another.
I have this memory from when I was very young, 2 or 3 years old maybe. I left alone on a strange round table, almost as if it were a medical exam. My parents were there, so was someone who looked like a doctor. But my mother has no idea what I'm talking about, and my father passed away before I could even think of asking him about it. And there was never an actual exam, at least not in my memory. They brought me into the room, they watched from another room, and that's all I remember.

I feel the poster did NOT have an out-of body experience, but it was an abuction. I totally believe in an after life, that many can leave their bodies --even at will-, and that many do have out of body experiences , but in this case, I feel it was more alien related.

They got what they needed, and maybe that's why she/he is now being left alone. Like you suggested, it could very well be DNA, sperm, etc.,

Many testimonies i've read- the person did have consciousness while 'floating' in the air above their beds, and they also recall being 'transported" into a ufo-- with very sterile cold surroundings and table they were placed on.

Then transported back. This poster- for whatever reason has a similar experience, but in their case, they were not given the opportunity to be 100 alert to where they were moving too or who was waiting for them.

I can say this with some confidence, because I actually was alert to see part of the "entity" standing near my bed.- it had reptile scales--and flesh was a very dark green. I forced my head to move towards it -THROUGH the paralisis- and was able to manage a glimpse of it. I dont know if it had evil intentions, and I now dont recall feeling any evil presence in regards to it--however, I've been wrong about people's characters before!

I felt it was alien, but had the impression aliens were only those Grey skinny dudes with large heads and almond eyes.

Now that i read more on differnt types of aliens, this one , I would say- definitly was a "Reptilian" type.
