I would definately get the full unrestricted version of Signs 4 if I were you. It will save you a lot of time and is pretty much essential for any FPSC developer regardless of experience.

The 'Rain & Snow' download from the decals section of the www.fpsfree.com website contains 2 sets of folders. The first is a folder containing the animated decals for rain and snow and the second folder contains a snow segment which will solve your lack of snow segments issue.
I've attached a screenshot of the snow segment texture with the snow decal next to it in Paint Shop Pro so you can get an idea. You could edit these as necessary to meet your requirements.
Also I've put together a quick video for you demonstrating the snow segments with some road segments I found and animated snow decals in a setting vaguely similar to the opening chapter of Fahrenheit. Obviously you will be taking much longer over re creation of the level, including buildings etc and doing it all properly but this will save you a little testing time finding out if you like whats already available for your level. I will upload the video immediately after this post for you.
Quote: "and whats lucid dreaming? any tuts? xD"
Lucid dreaming is 'the conscious perception of one's state while dreaming, resulting in a much clearer experience and sometimes enabling direct control over the content of the dream, a realistic world that is to some degree in the control of the dreamer. The complete experience from start to finish is called a lucid dream.
The validity of lucid dreaming as a scientifically verified phenomenon is well-established. Researchers such as Allan Hobson with his neurophysiological approach to dreaming have helped to push the understanding of lucid dreaming into a less speculative realm.'
Basically lucid dreaming is the ultimate virtual reality rush and you effectively experience your dreams in real time, totally concious of your own self and totally aware of the dream world around you. I've had several lucid dreams now and I will never look at dreaming in the same way again. Bottom line is it's amazing, completely natural and free.
The key thing is to train yourself to reality check aspects of your dreams which are referred to as 'dream signs' to the point where you can definitively say to yourself "oh my god im in a dream". once you have achieved this congratulations, you are now lucid and are about to experience a lucid dream.
Do yourself a favour and check out this website for more information on lucid dreaming techniques and general subject matter.
