I have been using a software called Brainwave Generator for the last year or so to attain waking lucid states and to intensify the lucid dreaming experience. It produces tones and bineural beats in headphones that can produce powerful alteration of consciousness (just be careful not to fall asleep with it running, it's confusing to wake up to it!) I browse through the archived user presets to find some of the most bizarre ones, but there are simple default settings that work just as well. Enjoy!
