Thread: Does realising you're dreaming meant that you are lucid dreaming?

I never had any lucid dream experiences. But there was once, just once. I was walking in a dream beside my idol. And suddenly I thought since this is a dream why don't I do something about it? And I went up and caught hold of my idol's hand and held it tight.

But everything was controlled by my dream afterwards.

So for like 1 second or so that I realised I was dreaming and taking a different action, does it mean that I'm lucid dreaming?
