As the title says...

I don't know much, I once had a demo of it. It largely dealt with the topic of sleeping and dreams.
You had a bald guy without a shirt and short blue pants, he wore sneakers.
There was a kind of overworld, that consisted of blue sky with rocks flying in it. The guy could fly in the way superman does, and that was his means of getting from one floating rock to another. Upon stepping on a rock he would then enter a level.
On these rocks there would be little blue people with hooked noses. They were enemies, and looked like some kind of fairy tale creature, but not a nice one.
It was 3D, and I gues it was around 98 or something like that. Similar timeframe to the first MDK, and graphically it was a little bit better.

Can anyone help me? Ist this game on GOG?

I don't believe this game is on here.

"Dreams: to Reality" by Cryo Interactive Entertainment, released in 1997/98 for PC and Sony Playstation.

that sound right?

It does, yes, Cryo rings a bell...

Thank you very much!

@Lugum: Appreciate the effort, but that really din't help me much ;-)

For what it's worth, it seems like this game could come to GOG, assuming EA still has the publishing rights and the game can be made compatible with modern machines.

Well it ruled out 650+ games. ;)
But yeah had dreams in mind, couldnt come up with the name though.

As I see it, it's already a DirectX game, so it should be possible.

As of now, I couldn't even find a demo for the game...
