The lucid exploration of dreams
techniques
remembering
Remembering dreams is a first step. Intent is a good first tool, most people improve their remembering by simply wanting to.
question reality
Lucidity appears after realizing you're in a dream. Multiple times a day, question if you're in the real, awaken world, by touching your nose, swiping your palm or trying to put a finger trough your hand.
affirmation and intent
Wish to be lucid in your dream, be that the last thing you think of before you fall asleep. Repeat to yourself "I will remember my dream"
notes
