Yo and welcome to dreamviews.
1: Sounds like dream might have been just unstable, stabilization techniques such as rubbing hands that you are using can help if it's that, or maybe you were just dizzy in dream, i've had some dreams where i was literally dizzy, in that case dream control it up to go away, like, drink anti-dizziness potion or something.
2: As splodeymissile said, definitely lucid, because you were aware that you were dreaming and even nice control and awareness, so congrats on your first!
