Yes. I had a few of those. And I can tell you that its a bit frustrating in the morning.
When you were so close to being lucid, but still so far away from it.

But again, that was in the period when I was not writing my dreams down, when I was not doing RCs everyday, basically not doing anything to achieve LD.
So I guess if it were to happen now, I'd be able to turn it into a real lucid dream (I hope )
