Well, where should I start?

I am not Lucid dreamer, I have "tried" it, but it wasn't very sucessful. The only thing that changed, is that I have become more focused on small details and contadictions that often occur in my dreams.

I have noticed I am dreaming more intensly when I have a lot on my mind(studing, exams,...) and for some reason I have a strange felling of Deja Vu on competly unsignificant things in my life, like siting on a bus, drinking soda,...

But the next example is alot more complicated. I am still slightly shocked by it.

I was having a dream about the internet (you may find this humorous, as I did and still do), a particural site, actully. This site.
In the dream, I found it very funny and I really don't know why, since it is far from the purpose the site "really" has.
The dream acured yesterday night and I didn't really pay much attention to it, until I actully found it, last night, and it scared the living crap out of me.
It was a lot bigger deal, that I had allready seen it before and was walking around my room completly shocked until for 4 in the morning.

My question, if this is normal?
I know of dreams somehow predicting near future events, but I never thought it would be to such big shock. Maybe it's the content (which isn't for everyone), but I really don't know.

P.S. Don't take the site so seriously. The guy who made it is actully a screenwriter who made a script out of this.
