Welcome To My Nightmare

I have a phobia of swimming in the ocean so this nightmare I had was probably one of the scariest. I woke up to my mom shaking me telling me the world was going to end that we had to leave and go to a safe place. I remember somehow getting into the car and heading to this hill by the ocean. There was a gigantic bubble that people were going into and it kept closing little by little. When we got there I realized that my father and my dogs were not with me and I panicked and told my mom she was crazy and why did she choose to leave without my dad and the dogs. I remember turning to my sister and telling her we had to go get my dad and the dogs. I felt my heart drop when she tells me "Dad is dead." I cry uncontrollably and tell her we have to get the dogs. She then took me by the hand and drags me to the shore and tells me home is that way, as she points at the open ocean. She goes in and starts swimming straight. I was there looking at the water that kept trying to drag me in. I panic and scream at my sister to come back that I'm scared. I somehow manage to get into the water and start swimming. I start looking all around me and all i see is the ocean. I feel something grab my feet and take me deep into the ocean.
