Stop having a certain dream that keeps reappearing?

I keeping having this dream every single night. It is of a farm with horses. I swear i recognise it but the only thing i can remember was writing a story about the place about 2 weeks ago. I have done everything i can think of to stop having these dreams such as chuck out every copy of the story i have, buy a gardian angel that goes under your pillow, buy a dream catcher. Do you know why i am having these dreams or how i can stop.
