Can you interpret a dream?

It was a single scenario. I was done for the day and there I was sitting on a staircase with my feet dangling over a clear cold sea.

As I was looking around, I saw a castle that looked like it was bombed during the war. I can clearly see the castle under water. It was so big and tall that it scared me a little but the scenery along with the abandoned castle was so majestic I could not stop but appreciate it.

Then, I was with someone and that someone said “It’s late and it’s getting cold.” Truth be told, and I can see ice forming on the top portions of the castle and so we stood up and left. Then I woke up.

Can you help me interpret this?
