Hey.
I've had the problem of it seeming like i was watching it through a tv, (and a rather rubbish one at that), before and i think its just down to practice and technique.
When you become lucid it is important to immediately "ground" yourself into the dream before you do anything else. If spinning didn't work for you then try another method, a good one is just to command "increase clarity NOW".
Most importantly, it is important to remember that if you want it to be clearer then you can make it clearer, the whole scene is created by your mind afterall.
If you feel like you're losing conciousness try doing a couple of reality checks, reminding yourself that this is a dream. Try to focus on something, for example your hands, and focus on how real and clear they look. Try to engage all your senses untill everything seems like it is 100% real. Don't settle for a groggy old lucid!
Good luck
