Dream of chased

I was in a house on an island, where we could not go outside, because the bull was around and kept chasing us. we were trapped inside the house on the island. the army came to take my mother and brother (he was sick) off the island to the hospital but the bull chased her around and inside the car, and she couldn't go. the bull was shaking my brother and scared him. the bull then heard my sister and I in the house and came after us
