Some evil people or Wizards flooded an entire island. A small one. And there was my house and my belongings! Luckily, I know how to fly, so I watched it all. There was a Castle on the island, and one of its towers was so high that its height was several times greater than the width of the island. But the Wizards were so ruthless that they managed to level even its very top with the water! Of course, it would be more logical to assume that they were submerging the island itself in the water, but in the dream, it looked more like the sea level rising, a tsunami, a storm.
It would be interesting to swim somewhere underwater in a submarine and come across a small island with a town, a Fortress, a Castle, and a long, surreal tower.
And before all of that, there was some other action involving these Wizards. And I was running around there, doing something, but I don't remember anymore.
