It's good that you can become lucid from FAs! Many times, I forget to do a reality check when I "wake up" and thus lose my lucidity. As for leaving your common surroundings, there are a lot of different ways to do it, like spinning. If you find that, even after you try to leave your familiar surroundings, you can't seem to get away from them, don't sweat it. Just go with the flow, and you'll be surprised where your dream can take you when you are focused on something else.
