so i dont know if this has been thought of, but i have an idea for inducing a lucid dream. you can tell me if it's a valid idea or not.

ill call it outside influence induced lucid dream. where someone will come to your side while youre in REM sleep and whisper into your ear, "you are dreaming" and that sort of thing. if you can hear it in your dream and it doesnt wake you up, maybe itd be a good way to induce lucid dreams for beginners.

just an idea. now good luck finding someone willing to wake up in the middle of the night so you can lucid dream.
