Artists block

Help.

I'm currently experiencing something I like to call artist-block.
I have thousands of ideas floating around in my head, but as soon as I try to get them down to paper, be it written or drawn, they just vanish. Gone. No matter how hard I try to hold on to them, they just keep slipping away. Taking a break and thinking about something else usually brings it all back again. But trying to work again proves almost impossible. I also tried using voice-notes to memorize my ideas, but to no avail. The recorder starts and my mind goes blank.
Help me. Send me ideas, hints or anything that could get me out of this misery.
It can be pretty frustrating having an imagination gone wild and no chance to visualize the stuff. Most of the stuff is sick shit, but fun none the less :). But with enough ideas in your brain and no way to get it out, sometimes it feels like your head is going to explode.

Cheers and good lovin' to you all,

Chris
