Hello, I am new to this site and I was hoping someone could help me find the meaning of this dream.

Before I explain it I should say the reason why I am asking for a meaning of this dream is because during it I was very aware. It is definitely the most vivid and detailed dream ive ever had.

Ok. So i woke up in this large wilderness. The ground and scenery was white except the trees, for some reason they were still green. I think it was snow but I am not sure. I got up out of this random bed with this nightstand next to it that very closely imitates my bed in real life. The bed and stand were on this short pedestal. I looked at the horizon and there were a lot of mountains, but get this: They were upside down. I was very surprised and felt like I wanted to tell someone, I looked around but I was alone. There were also normal mountains, they were white but the upside down ones were earthy, like brownish. There were 3 rows of normal mountains counting the cliff I woke up on. There was two valleys separating the mountains. The last row met this huge gap in the air. It was like this really white and bright light, then the upside down mountains started. It kind of looked like teeth. [There was a lapse in my dream here] I assume I was exploring the area because I started remembering again when I was walking up this path up the last row of mountains. It was graveled for a vehicle. I reached the top of the path and it met a flat in the mountain with this big cabin-like house in the flat. There was no snow on anything in the flat, only the mountain on the outside of it. I started to walk to the house but this old man came out of nowhere and started yelling something at me I couldnt understand and shooing me away with his hands. I apologized and turned around. That is when the dream ended.
I noticed that the old man was wearing very warm clothing, like it was cold outside. But I wasnt cold at all.
