Hi and welcome to DV! When you know you're dreaming, it's a Lucid Dream. It's that simple So yes, you were Lucid. Also, the thing you're using is called a "Dream Sign". It's a re-occuring thing in your dreams, and you've trained yourself into questioning your reality whenever you experience it. This can be done with alot of things, and is a part of the DILD technique.

Look them all up in the Wiki - Dreamviews Lucid Dreaming Community & Resource if you like, it's got great tutorials

If you have anything else you feel like asking, don't hesitate to!
