I have only tried it a few times and have been unsuccessful..the way i discovered was, i tried to find a way to make dreams more vivid and i stumbled upon this, then after having no luck i experienced something crazy. i would normally go to bed around 10:45, then i would wake up around 7:00 and play hookie from school, then i would go back to bed about 7:35 en have loud ringing in my ears and a feeling of floating out of my body, but when i try to have that feeling, i am unsuccessful. (what am i doing wrong?? what are some major tips that would help me???)
