It sounds like you need to evaluate your expectations of lucid dreaming. If I understand your post correctly, you've been trying for FIVE nights and haven't gotten 'high definition' dreams with complete control. It usually takes a lot of practice and discipline to be successful at anything. Now I don't know what techniques you've tried or how much you've read up on lucid dreaming, but I would suggest reading and learning as much as you can on the subject. Whether its tutorials on this site or books such as 'Exploring the World of Lucid Dreaming', there is a wealth of information out there. Learn as much as you can about how dreams work, how our brains work, and what you can do to improve your chances (and just as importantly understand WHY they could improve your chances). And read other people's experiences. Each person is different and one technique might work well for one person but not another.
