A Japanese "castle" that I explored with a group of others?

Sailboating somewhere (not me driving) off the coast. The weather looked like it was getting pretty bad when we left (dark clouds approaching, already pretty high waves), so I wondered if this was really a good idea.

I was with some kid in the desert, next to a large structure. We wanted to leave. I started climbing a sandy hill, but the sand was deep and hard to move through. The hill suddenly turned extremely steep (90°), so it was impossible. A kid (possibly accompanied by another) appeared on top, seething with anger. He was mad at the kid who was with me, I think. I asked him why he was so angry. He replied that he had shown a potential customer the apartment, and that customer didn't want to rent it. Or something like it. He was in our way, and I didn't want to be trapped in there forever (it was the only way out), soI walked up to the wall of sand and kicked it. The sand collapsed, and the kid on top fell down with it. He immediately attacked me, possibly wielding some kind of stick or bat. I kept fighting, until I realized I must have been 15 years older than this kid and could easily overpower him. With some help of the other kid (he was possibly inspired by "Piggy" from Lord of the Flies, I watched the 1990 film yesterday and am still reading the book) I got him on the ground. He was swearing, but I grabbed his throat with both hands, and in the heat of the moment felt the desire to kill him. I squeezed hard, he went red and coughed a bit. I leaned closer, bit into his neck and savagely ripped out a chunk of flesh. Last thing I remember is me saying "Die, you little shit!". Then I woke up.
