Brief vision of a beautiful place?

The other day I saw in my mind briefly, a lovely open place, with all depths of field in focus, I overlooked a path from like 40 metres up, looking at a man part of the way to a gate, vast like clouds, of gold, leaning to the left, and with trunk like ridges in it and a gold on the left, and there was the path going through, with a man walking into it. I think the path was was white and maybe green on the sides. The place seemed vast and lovely, reminding me of the new subway in Sydney Australia, caverns 200 metres down, and tunnels for trains hundreds of metres into the distance.

I don't know if it is from God or my subconscious mind. I don't know what it means.
