No problem! Well I don't know which techniques you use to have lucid dreams. But you can astral project/have obe's from Sleep Paralysis or even meditation. Do you induce sleep paralysis or do you meditate? And I would say, take a break from Lucid Dreaming. Maybe when you return some day into the dream world, he might be gone forever. Cause if you can't fight it, I honestly don't know what else you could do. D:
