This is a bit controversial for me. I know from experience that I have and always will have problems keeping a dream journal. I have come to the conclusion that it makes me more aware of my dreams and improves recall, but I don't think a dream journal is necessary to do this however. I hardly ever find myself looking back through it, I only keep it to improve recall. So couldn't I just try to recall my dreams upon waking, but not make written note of them? I know a DJ is crucial to recognize dream signs, but I have never used dream signs. I usually just realize I am dreaming randomly. If there are anymore pros to keeping a dream journal other than what I have listed, please list them. I know having a written record of your dreams is nice, but is it necessary?
