Astronomy tour and finger shadows in the sky

I'm traveling in a car to somewhere in Georgia with my dad. We're going to something like a guided fishing tour except the guide will give us an astronomy tour.

I'm waking up from a nap in the back seat as we stop to take a break. We're in the mountains and looking at the setting sun through a small natural stone arch. I discover the stone arch allows me to do finger shadows across the entire sky if I get the angle just right - it's difficult because the angle changes along with the setting sun. For a brief moment, my reflection fills up the whole shy but I wonder if it was an illusion caused by a glass pane which covers the whole opening in the stone arch.

I look out over the mountains admiring their beauty - there are lots of people who have come to watch the sun set at this spot we seemed to choose at random. There's a young kid pitching a baseball in a crowded area. He's throwing wild pitches and I make him stop, afraid he'll hurt someone. A grotesquely giant man with no torso from the kid's group stands up and silently intimidates me. I tell him, "So great you're really big. I'm just trying to make sure nobody gets hurt."

The giant seems satisfied and sits back down, but there's a bad feeling coming from the whole group. Someone is throwing baseballs and hitting golf balls at me from somewhere down a mountain path I can't see. None of them hit me and I pretend not to notice. I maliciously kick several golf balls over a cliff.

Walking toward the cliff, I suddenly realize it will be difficult to climb back out. It's suddenly snowy and icy. My dad comes along and I try to warn him to stop because he'll get stuck too if he keeps walking towards me. He slips and I grab him. I try to pull him towards me but he slips even closer to the cliff. I wonder if he's going to go over the cliff and if he'll die.
