We can all speak faster than we can write. I recommend a recorder of sorts so when you wake you can blast out as much as possible before you forget too much of your dream... I've found that to be a huge help because writing as soojn as I wake is a bit screwed up to say the least... Also I find when I listen to it later that day it brings about even more memories of the dream I was recording in the first place... Then if you want write it down later!
