I'm worried. Please interpret my dream?

I had a weird dream while napping earlier. It was normal, me, my parents and my brother were on vacation. At some huge magical-ish place. But then I went to some cave and there was a lady with people who worked under her, kind of like slaves. There's some stuff I don't remember, but something happened and she sent all of us in this hot roller cart thing (you know those carts on tracks, like in Minecraft). The place was hot and the bottom of the cart was hot. I was sent into along with her workers/slaves. After a while of being in there, I saw people around me beginning to look dried up to the point that they can't move and they were just dried up looking statues. I was the only one who was actually immune to all of it. I didn't get dried up, I survived.
Then I woke up. What did my dream mean? Please tell me!
