Hi Guys

I am very new to this area with lucid dreaming, but I've wanted to do it for a while so.
Two days ago I had a very clear dream. I remember I was on my way to the birthday of my grandfather. On the way up the stairs to the door, I suddenly became very dizzy. So dizzy that I could not see anything, and everything was just blurry.

Then I wake up. When I fall asleep again I'm back where I was in the dream. Then I think: this is just a dream.
At the same time I think about it, it feels like I'm falling into a dark tunnel, and all I hear is a massive loud sound.
Again, I wake up, notice that my heart pumps very fast and I'm out of breath.

Was this the beginning of a lucid dream?
