In a cave

One day when I was 2 or 3, I went to a cave. At the entrance there were 8 steps going down. I saw lots of stalactites and stalagmites, then we went deeper into the cave. I saw a spiraling staircase made of rock going up. It isn't a real spiral staircase, it is a stalagmite about 20 feet tall. We went past that and saw some crystals. It was amazing! I don't really remember much after that except we went to this pool of icy water and someone flashed a red light and I tried to catch it. It kept flicking off so I couldn't catch it and then appeared on another space. That is all I remember.
