I could see the beach from a distance. I saw a huge wave coming towards the beach and I knew the people on the beach were in danger. I attempted to shout to get them to run for safety but no-one heard me. As the wave got closer it turned into thick black oil. The black oil splashed over everyone on the beach. They were all covered by this thick black oil. I kinda felt relived as I thought the wave would have drawn someone into the sea and they could have drowned. I then woke up.
