Best exorcise is to keep a dream Journal and write in it every morning as soon as you get up from bed (not up as in whole body, but just your chest, let your body stay in the bed). Keep a clear mind (don't touch caffeine), and tell yourself every night and morning that "you can" lucid dream, don't give up or doubt yourself otherwise your chances drop. I would suggest attempting a WILD (if you can handle the odd sleeping schedule) for best results, unless you're a natural dreamer, it'll take a ton of practice before getting anywhere, patience is key. My first time attempting it, it took me about 3 weeks of practice, and 3 weeks of quitting/forgetfulness before I had my first dream, it was sick as hell when it finally happened too.
