This is a dream my 15 year old son Elliott had. I’m sorry it’s quite long, I just feel it might be a significant dream for his life/future and I need help interpreting its meaning.

This is the dream:
Im camping with family. We were happy and relaxed.
My Uncle and I get on our mountain bikes and ride around the campsite.
A man walked over and was talking to us, he showed us this grass wall, large jump thing that he had just built directly in front of our tents and cars.
We get mad and I told him “No you can’t build that here, we don’t own this place. You will get us in trouble!”
The man didn’t care and kept building it anyway.
We were all very annoyed, so my Uncle, Pop, Dad and I hopped in our 4 wheel drive car and drive away up a mountain that was near by.
The track up the mountain turns into a fire trail track. We stop halfway up because we think we’re lost.
Up ahead we see these men on mountain bikes come racing down the track really fast towards us. They try to brake but it’s too late. They crash into our car.
We get out to help them. One of them broke their legs, so my Dad and I walk off to find help.
We hike further up the mountain, the trees start to became denser and turn into thick jungle. We keep going up the mountain, we reach a very tall rock wall section.
We climb up the tall rock part and reach the very top of the mountain, we’re so high up, above all of the trees and the view looks very beautiful.
We are taking in the view for a moment when we hear a loud bang above us. We look up and see the sky starting to open up..it looks like a big crack in the sky.
A bridge appears across the sky. My Dad and I are amazed!! The bridge leads into a big white circle landing.
I then hear a voice saying “it time”. I say to my Dad “Im not ready”. He says “Well this is it!”
Suddenly I get sucked up and everything went black for a minuet, then I land in this palace/castle place.
Everything is gold, the floors are white marble with red carpet runway on top.
I follow the carpet and go up the stairs. I have an awesome feeling and think this place is the great!
I walk around and explore, there’s lots of people everywhere and everyones really happy, I think to myself, this isn’t so bad after all.

All of a something goes wrong? I suddenly leave and im back at the campsite. Then moments later I’m immediately back at the palace/castle entry again but this time everything is different and bad.
I follow the same path inside bit nothing is gold anymore. There is no red Capet, the floor is still white marble but the rest was gone. I go upstairs again and notice this time all the people are now lined in a straight line, kneeling, all looking in the same direction outside towards the mountain from where I had first came from.
Nobody notices or is looking at the other side of the palace to see the big angry ogre that’s now down stairs
It has a big wooden hammer in its hands and is destroying all the pillars that are holding up the second floor.
I get mad at the ogre and say “what are you doing!” but it dosnt answer me.
It then goes around in a circle knocking out all the Pilar’s one by one. It accidentally misses one of the pillars. That annoyed me that he misses one because I think to myself “if you’re going to do the job, you may as well do it properly” then I go and knock down the pillars he missed.
