I've used hypnosis for inducing lucid dreams many times, but I was just wondering what people's thoughts are on the idea of using self-hypnosis whilst actually in a lucid dream? Do you think it could have the potential for being even more effective than hypnosis in the waking state?

I just happened to notice how profoundly relaxed I am if I lie down in the dream world, like my body feels so floaty and euphoric and I feel so carefree and relaxed.

I guess that you wouldn't even need to induce the hypnotic trance because you're effectively already in one, seeing as how you're asleep and dreaming. You could just lie down in the dream world, float away into a void and say what you aim to achieve via the hypnosis.

Has anyone ever done anything like that?

e.g. You could even try the HILD technique in a lucid dream... Just get one lucid dream and then lie down, relax and say, with meaning and assertion, something like "Every time I dream, I will recognise that it is a dream and will become lucid". Anyone tried that?
