It sounds a little off to me... scary stuff. Like meddling in areas we really should leave alone? What if you get addicted to lucidity? And, what can you do in that state - where do you 'go'? What purpose would it serve?

It sounds very different from daydreaming and drifting in thought (unintentional) while you are still connected to your body and movements. Those I have. I even get some sort of visions, unrehearsed. Dreams too. But lucid dreams... unless it is just at that moment where you're drifting in and out of deep sleep and you can hear people around you and are aware to some degree but already drifting away so you don't respond...

Walaikumsalam, it does sound scary. But it really isn't. and it is very different from day dreaming and drifting in thought. because your body is sleeping but you are full awake in yourself. I don't think lucid addiction would be bad. There were alot of experiments carried out and its a natural phenomena.
In the state basically you can do anything you imagine, fly, jump as high as you can and stuff you can't do in reality.
Where do you 'go'? No where, just in sleep, no I have heard that once your asleep your ruh leaves. So with respect to where your ruh is, I do not know.
Purpose, I am really not sure about it. But lucid dreaming is mostly recommended to those who have alot of bad dreams
