Oh boy. I have been visited twice, so far as I can tell, by what people have been calling "Greys". They are almost humanoid, in that they have two arms and legs, and a head like ours, but they are very different in appearance. Their head is large, and shaped like an inverted teardrop. They have huge, black almond shaped eyes, and a nearly unnoticeable mouth and nose. I haven't even noticed any ears, so to speak, and they have no hair like we do. Their bodies are thin, and small compared to ours, with a small torso, and thin elongated arms, with elongated bony fingers on their hands. Same with the legs, I suppose, but I rarely focused on that part of their bodies. Their skin was a sickly grey, with a tinge of green.
They came, both times that I recall, when I was lightly sleeping. I guess it's easier to sneak up on a person when they are unawares like that. Both times, they immobilized me somehow, and I could only look around with my eyes, as I shook in the most absolute fear I have ever felt. Both times they were surrounded by a thick fog, so I couldn't really see them in fine detail, but I could see how the basically looked, as I described above. They seem to communicate to one another with an almost insect like clicking language I couldn't understand.
They are hideous malevolent creatures, devoid of any real souls, and only seek to cause pain and suffering, but I guess one or two do feel remorse for their species' experimentation on us. The first time they abducted me, the one in charge of carrying me to the vessel from whence they came actually seemed to feel sorry for me, and tried to comfort me with a kiss on the forehead, not that it did much in any sense. I was still terrified out of my gourd.
In fact, by simply writing this, I feel an increase in fear. I am almost at the point of shaking, and my heart is racing. Well, time to look at pictures of cute and cuddly kittens and puppies for a while.
