Cave?

Yeah, It's something I'd like to do in length. There is such weird things in dream caves.

I had this one.

I'm outside on the street, it's night time, and it's winter. Not sure what I was doing, waiting for something, I think. While I was waiting I was passing the time by making snowballs, and throwing them at a snowbank across the street. I notice a dark hole in the side of the snowbank. It looks like the opening to a cave/fort, that maybe some kids had made. Cool, I want to check it out. I loved making those when I was a kid.
I have my flashlight, but the battery is a little dim. I take it to go check out the cave.

I climb the side of the bank, and enter. I'm very amazed by what I find. It's a huge beautiful cavern inside, not of snow, but of rock. I'm standing on the edge of a very high underground cliff. The place is dimly lit by a bluish glow, from some kind of glowing blue liquid river, far, far, below. I feel a wave of heat rising from below. Not uncomfortable at all, it feels very nice. The formations of rock, are incredible. And in places I can see that there is vegetation, giant leafy plants. I can tell that this is some kind of cave system that goes on indefinitely, deep beneath the earth.

Immediately upon entering this place, I know that this can not be real. There is no way all this can be inside of a snowbank, on the side of the road. A couple of times I repeat to myself, "This can't be real." I then reach up to pinch my nose, to check if I'm dreaming. Sure enough, I can easily breath.

Without hesitation, I take a running leap off the side of the cliff. As my feet leave the ground, I wonder if maybe I decided it was a dream to easily, and I feel a slight tingling in my stomach as I begin to fall. But no, I can fly. I swoop down across the canyon, and around this tall pillar of flowing twisted rock that is rising up from below.
Then I begin kind of drift/glide in a circular descent around the towering column.

It's getting darker though, I can barely see anything now. I try to shine my flashlight, but it's not giving off much light. It's a dream flashlight, no wonder it's not working right I think, and I toss the useless thing. A couple of times things start to get brighter, but when I focus on the lit areas, it goes dark again. And I wonder if it gets too dark, if the dream will destabilize on me. In the darkness off to my left , I can hear a strange clicking sound. I can tell that there is some kind of unknown creature making the sound. I think, Wow, this is going to be so cool weird creatures and all.
But then I abruptly wake.

Then I fall back to sleep and return to the same cave.

There is a little bit more going on this time. there was some weird stuff going on and I'm with my brother. But then I see the cave opening again, and I remember it. I say to my brother. "You have to check this out. There is a whole other world inside this snowbank."

I'm not sure if I was Lucid before entering with my brother, but I think I must have been. I took my brother by the arm and dragged him into the cave. I just had to show him this place. And as I enter, I know for sure I was Lucid because I was thinking about what an incredible, and rare opportunity it was to be returning to the same dream place again. And I think about the one time this happened to me before. And I'm very excited about getting to try this again.

I pull my brother to the edge of the underground cliff. And with out even mentioning that this is a dream. I know he is going to freak, but I let go of his arm and leap off into open air. Everything is pretty much the same, but there is much more light this time, I can see easily. I'm so excited as a fall and swoop down across the canyon yelling, "Woooooohoooooo!" I swoop around the tall pillar of flowing rock again, and then to my left, I can see the creature that I could only hear in the darkness of the previous dream. It's a giant green lizard like thing, crawling across the side of the cavern wall.
Thrilled to see it, I begin flying in that direction intending to interact with the thing in some way. But as I get closer I abruptly wake.
