Dream of father, mad, swim, dolphins

First on a ride that flies but there was no safety rail and i am holding on like mad. I fly off and a weird man approaches and tells me i have to swim across the water to the other dock. As i dive in i see a man fishing for dolphins. One swims really fast to the surface so i race to the dock and climb out. He sends me and my family through a door and down a corridor. As we walk i notice a goat is staring behind us and whenever i try to look it hides. We reach the end of the corridor and go through the only unlocked door. My dad is staring at the wall and as i turn around from him i notice a figure dressed in a trench coat, wearing a gas mask walking towards us. As is gets closer it throws a pair of scissors at me and attacks my dad with garden shears. I pick the scissors up and throw them back but nothing happened. My dad still trying to fight the figure off i pick a shovel up and swing the sharp edge at the figures head several times. My brother screams from the previous corridor, i poke my head out the door and see there is another figure attacking him. I knew my best chances were to get dad help so he could help save my brother. After several more hits the figure stops attacking my father and walks towards me. My dad falls to the ground gasping for air, i am battling this thing. Eventually i kill it and run to the corridor to find my brother has gone and so has the second figure.
