Here's a little trick I have learned. Read some passages of your DJ directly before going to sleep. Why? Because our big human brain assimilates the days experiences during dreams, including reading your DJ. Reading your DJ can make you hype-aware of things that can only happen in dreams. So, lets say, when you see an elephant fly in your dream state you might (and I emphasize might) see this as something that can only happen in a dream. Good luck to you!
