If you are conscious of it being a dream, then it is considered a lucid dream, regardless of whether or not you have control. I've had lucid dreams where I'm just taken along for the ride and watch things play out without my control, even though I know I'm dreaming. ...I even had one just last night where I spent a little bit of my LD with no control whatsoever, so it's pretty common.

But you seem like you had a little bit of control, since you remembered to stabilize yourself when you started losing lucidity.

Also, you can forget parts of lucid dreams just as you would regular dreams, or forget them entirely. ...which always sucks. I wonder how many times I've gone lucid just to not remember it when I wake up? And forgetting minor details is normal, too. I can't even begin to tell you how many times I've remembered my lucids and had no idea how I went from one scene to another.
