This happened to me about three years ago...and it still makes me feel extremely weird.
Maybe you guy's will help me out with an answer?

I was on an airplane, going to Alaska with my families. We were in the southern part of Alaska, the Jueno (sp?) area.
Around there, there is a place with about a million small lakes. Kind of like that one place in the 1st Narnia book, only without the trees.

So there were tons of small lakes on this plain. Kinda...swampish? Reminds me of the Marshes in The Lord of the Rings....
As I was staring out the window, I was extremely sleepy, but I didn't want to sleep because the view was amazing. I loved looking at the water....
FLASH!
I was standing on the plain, looking into the water. Or was it me?
Suddenly I heard a voice, speaking words I cannot remember. It was like a whisper. The tone was serious, as if a warning...
I looked up and saw the plane I was in, and
FLASH!
I jumped in my seat.
It was as if someone had shocked me. I would have fallen off the seat if not for my seatbelt.
I felt so dazed, lost, and totally confused. I was so frantic I was nearly paranoid.


So, what do you guys think? I have no clue at ALL what it was, but I do know that it felt so real, but so sudden and flashy, like a movie or something...
