I think that this website uses science a lot. For any claim, you debate with 'proofs'. Look, lot of people are having apocalyptic dreams and visions about 2012 and… is proved that some dreams become real, or warn us about something in our life, but it might warn our entire world. Look at the southafrican Desteni, Barbara Hand Clow and other people. Is a coincidence or something more. I'm not saying that the world is going to be destroyed in 2012, but those people deserves attention and cannot be ignored.
It's often a rarity that dreams or, "visions" are an accurate view of the "future".
Déjà vu is a more commonplace, and largely misunderstood side effect of dreams, especially dreams of things that may have happened in the past. Three months ago, I had a dream that I was baking an apple pie with a family member, just as I have done several times throughout the years. Today, I'm baking apple pies for Christmas, with family. Déjà vu, of course, but does that really mean anything significant?
It's actually ignorant to assume that our brains are giving specific individuals glimpses of a doomed future, while it's true that a doomed future lingers just around the corner (that corner being several Billion years into the future), it's still completely speculative that ones dream-state is even sufficient enough to be scientifically tested.
Before you say anything.. Yes. We can test your dream-state.
The time when your brain is most active is during a nifty little period called "REM Sleep" or, Rapid Eye Movement, it's at this point that the imaginative portions of your brain are at their highest, producing dreams, most often, dreams that we tend not to remember. More often than not, we remember dreams usually because they're traumatic in one form or, another, be it emotionally or, mentally traumatic (yes, you can actually become traumatized by a dream).
It's virtually impossible to prove that dreams do indeed come true, the fact is that there's simply not enough data on the subject to even begin to say that it's proven. As someone who has studied in psychology, it's nonsense to say that it's "proven" that dreams do come true.
The brain often reflects our emotions. Moody? You'll most likely have a distressing dream, perhaps a dream of murder or, of apocalyptic nature or, just a very, very confusing nightmare. Good mood? You'll most likely have a dream that makes you laugh in your sleep or, dream of a good time in your past. Your brain reflects your emotions by digging up a random sequence of memories. This is why people often see wolves or, animals in their dreams, while others see loved ones or, past events in their dreams. If someone sees something apocalyptic in nature in their dreams, then it's most likely because they've seen it somewhere before. Television, most likely or, they've read it in a novel.
That's simply the facts.
There are somethings you can't explain, like Nazca stuff.
I assume you're speaking of the Nazca Lines.
The creation of the "Nazca lines" are as ambiguous as the creation of the pyramids or, the creation of Stonehenge.
The creation of these points are open to fools who attempt to link extra-terrestrials to them or, to fools who attempt to link a doomsday prophecy to them.
The fact is simply this:
Sights such as these, were usually created for religious purposes, especially in those times.
It's assumed that the Nazca Lines (like Stonehenge) was created as sacred paths that the Nazca peoples once walked as part of their rituals, it's not uncommon that ancients of any part of the world would build structures or, monuments for their rituals to take place on, in or, around. More often than not, this was the sole purpose of most of the structures that people can't seem to explain.
The sad truth is that modern people can't get their heads out of science fiction novels or, doomsday novels to actually take a step back and simply say "Hey.. This was designed for a ritualistic purpose", instead of looking for the obvious, they only look for what they want to see, and at this point in time, they want to see "OMG!!! It's a sign of the end or, intelligent life beyond our planet!"
Sad truth of life.
