I feel like I could change the world if I had the same levels of inspiration during the day that I have at night.
Then again, the last note I put in my phone is:
"Motorcycles acting like dogs, excited to see each other etc."
So it's probably for the best that it's restricted to night times...
But yeah as others have said, you need a way to get your thoughts down there and then, even if it's in note form - my phone is perfect for that.
