i think i may have stumbled upon a little auto-suggestion…I always date my dreams and title them so one day i thought why not just start a entry in my DJ the night before so i dont have to think about the date in the morning 
(cause im all groggy and what not) so i decided to do that and every day this week i have been doing so thinking hey i will have a dream tomorrow i better put and entry in and everyday this week i have been having multiple dreams that are quite vivid… i hope im making sense here lol 
Yeah I see how this would work or worked for you. But just remember that it’s all about believing, so keep your attitude of “Hey, I’m gonna have a dream tonight!” up instead of writing down tomorrow’s date by habit, because that’s what I do and it’s not really helping my DR.
