See? Exactly what I was posting about earlier. YOU believe so it is unexplainable to you, but it is perfectly easy to explain by me.
Your wife saying goodbye in your dreams before she dies. Easy, you know she's dying, so when you found out she was dying, you could have had that same dream 200 times before, you just remember it now because it is significant.
Catching something out of the corner of your eye and turning to look and not seeing anything. Easy, your mind is playing tricks on you. Not "supernatural" in any way shape or form. Just like getting wasted on acid and seeing sound and hearing colours....it's just a mind trip.
A better way to explain it is:
Scientists at Johns Hopkins (I think it was) did a little experiment by hooking up a bunch of people to brain scanners then they had them do things like ride roller coasters. Then they had them sleep and taught them how to control their dreams (it is pretty easy to do actually). They found that brain wave activity is exactly the same during the real experience, and the dream. That means the imagined experience affects you exactly like a real experience. That means that the imagined image out of the corner of your eye is experienced as if it was real. Your brain is telling you they are both exactly the same.....
As for not posting much, just because there are people here who don't think exactly like you do only makes it a much more interesting place. How boring would life be if everyone thought exactly the same???
