Yea, never assume you will remember anything from a dream, later on. I wake up and try and write things down. I wrote something I thought was important down from a dream today. Wrote it in the dark or idk even know -- it is so sloppy I can't even read it. And I have no idea what it was supposed to be. No memory of what was going on except it seemed important. The only thing I can read is on the back of the page and is 'Later: Hercules' Golden Apples. The rest is lost." And I remember feeling frustrated that I couldn't even get the rest upon waking and that I was aware the note about the apples was going to be insufficient without the rest.
