Well, you'll hate my answer because it's based in something that's less esoteric than beings from somewhere else, or from here.
I honestly think that it's psychological. I've had sleep paralysis that has induced visions of terrible things poking and prodding at me, but I know that it's sleep paralysis because that's been proven. Who's to say that what you're seeing isn't psychological? I know that you don't believe that, but you have to see it from my perspective as well.
And yes, I believe in UFOs insomuch as they are objects in the sky that are unidentified.
That explanation fails for several reasons. There are a lot of reasons why it's not psychological. Experts have pretty much proven this, even when they were trying to debunk it. One reason is that in a LOT of cases, more than one person is involved. There are also many cases involving some kind of physical evidence. There have been cases where someone that didn't know the abductee witnessed the abduction (such as the case in NYC studied by Hopkins).
Sleep paralysis has NOT been proven, show us where it has. It's also a lame excuse, and doesn't explain why someone would have these experiences. Especially when they are wide awake and not even in bed. I was wide awake, and even once standing, during my experiences.
And lastly none of these things can explain stuff like missing time, or people being imparted with knowledge they didn't have before the experience. Some people have even become psychic afterwards, but then you probably don't believe in that either.
I don't believe you, because there's nothing in what you're saying that is true. It's your opinion. People who actually study this stuff have a different opinion. Listen to the current show for some of those opinions. And it doesn't explain my experiences, or many others. Who's to say that what I'm seeing (I didn't see anything) isn't psychological? A few psychologists and psychiatrists, that's who. I'm quite normal. I don't suffer from delusions, and I have a high IQ.
John Mack, and other psychologists have the same opinion about abductees. They are normal people, and there is no psychosis involved.
People have been trying to debunk this stuff for a long time, and they always fail. The unfortunate part is no real study of the subject will be done with this attitude.
You have demonstrated that you are a fundamentalist skeptic. You have your mind made up based on zero research. In essence you are saying "it's not real because I don't believe it". At least read a few good books on the subject or listen to the Paracast.
Until you make a sensible comment showing you are anything but a fundamentalist skeptic, I will not respond to any more of your posts. It's a waste of my time. You can't lean anything with a closed mind.
You might be uncomfortable with it, but this is what's going on to many people.
