No recall tonight.
You know I had no dream recall for a few days, and then I read a comment, I think it was either CanisLucidus or BrandonBoss or Scionox who said yesterday that if one only practices dream journal as only tool for dream recall than it tends to fluctuate, and so I looked again at the tutorial for dream recall suggestions, and one of the things it suggested was to mantra "I remember my dreams" before going to bed, so I did, and tonight I remembered a long dream. So, I recommend that wholeheartedly.
Thanks for the advice, I'll try it tonight.
