Dream journal
I often wake up in the morning more tired than when I went to bed at night. I don't always recall my dreams completely. Oftentimes I can only remember the tailend and as the day progresses I forget even that.
This is why I set up this dream journal. Upon waking the first thing I ever do is go to my PC I may as well get my dreams written down while I can. Then I can go back and read it and maybe figure it out.
