Continuous dream once a year

For the past five years I have had the weirdest dream experience. Once every June, I have this dream that continues where it left off the last year. I have no clue how it happens but they scare the s**t of of me every time. It started off with me walking down a dirt road and I see a farmer and we start talking about something(I don't remember what) when I leave to keep walking I look back and see this cloud of dust far away. After about walking for a mile, I end up in a city like New York in a playground with lots of kids. We are all just playing on the swings for a while and eventually the cloud gets closer and it's two giant Bulls. All of the kids go to their parents and drive away but I am left alone on the playground be, hiding under it in fear... About a year later I dream that the Bulls find me so I run all over and hide in a liquor store. They eventually corner me and they charge... Once again I wake up and a year later I fall asleep and crash!! I dive out of the way of the Bulls and all of the drinks fall to the ground and shatter. I am scared for my life running from these Bulls and I hop in a taxi... I wake up. The next two were basically me running from them. This year since I know about lucid dreaming I will try to recognize it and have a little fun :)
