Dream journals are personal and all your own. I suggest having two sections, one where you record dreams, and another where you list your common symbols, recurring themes, anything extraordinary that occurs, etc.
This will be your own window into your soul, and developing your own personal dream dictionary of sorts is far more effective than using a standard dream dictionary. Although some meanings are somewhat universal, that isn’t necessarily true.
I suggest a small journal that can be kept easily and unobtrusively by your bedside. This will ensure easy access enabling you to record more of your dream experiences.
If you find that writing dreams down doesn’t work for you and you are able, buy a small tape recorder and keep that by your bed. When you wake you can record a message for yourself. This may also help those of you who forget very quickly upon waking.
