That's awesome and really interesting! I totally get your "stream of conciousness" and I sometimes wish there was a device to write down what's going on in my brain one on one. Since I'm not the fastest typer I sometimes use a dictaphone (but not for freewrite so far). I usually jump right into a scene and I'm then writing down the scene either as an observer or as a person who's actually in the scene. Someone convinced me to post my associative writing thing on "switch", anyway, but my stories are usually more like my freewrite on "snake" (feel free to check it out if you like ;))
