remembering

I have ideas all the time in the middle of the night. I am usually too tired to get up and write them down and then they vanish by morning. All that is left is a little fog of a trace that I can remember and it is not enough to actually get what the idea was. I discovered a new way to remember what I thought of without getting up. I get the idea then I put music to it. Any music that I think of at the time with Lyrics. In the morning the song is easy to remember and the new idea is attached to it. Voila idea remembered without getting up and writing it down.
Your mind just needs a hook that you already know to hang the new info on. This works as a study habit but I did not know it would work in the middle of the night.
