I think it is just temporary. You should be able to dream normally after a few days.
First thing to say, it is your mind. You don't really fight it. You explore and sometimes you can get lost in your own labyrinth.
I also experienced sometimes a rough rejection from subconscious. (threw me away to the river with Star Wars style force etc.) Maybe you need to go from another side. Try to find another way to achieve what you want in dreaming state. You just came to the wall so go back a bit and take another way.
The reason you have blocked dreams (or just a dream memory?) is your own mind. It's like when you fail at something, you create a block in your mind and next time you are terrified and don't want to try anything like it again.
