Hey ryman,
If you knew that you were dreaming, if you were aware on some level, then you were lucid. An LD doesn't have to start by, or even contain, a reality check for it to be considered an LD... Just about all of my own lucids started with me just having a random epiphany halfway through the dream.

If you were just acting like you knew you were dreaming without actually feeling yourself having a mental presence or consciousness in the dream, it may not have been a lucid.
