Natural Disaster Dream

Hello, I am new here but I had a very vivid dream that stuck with me. I was wondering if someone can help me interpret it.

The Dream: The dream starts with me sitting on a beach with my girlfriend. It is night time, and the air is cool and windy and feels good. Behind us is a jagged cliff face that is about 60-70 feet high. We are watching the waves waves crash on the beach. They are strong but not dangerous. I feel relaxed at this time. Along the beach are many other people, doing the same thing me and my girlfriend are doing, sitting on blankets and towels and relaxing watching the waves crash. As I look at the crowd I lose sight of the waves. When I look back at the beach I see a dark 30-40 foot tidal wave approaching in the darkness. Some people are alerted, many people just sit in shock or ignorance. My girlfriend is a bit scared, but not as scared as she should be. At this moment I become afraid, I know we cannot escape to high ground and that jagged cliff face behind us with cut us to pieces if slammed into it by the wave. I grab my girlfriend's hand and run towards the wave. I begin swimming head long up and into the wave as far and hard as I can go. The water is cool. It goes over my head and I spin around and tumble under water like I'm in a washing machine. When I pop out, I'm relieved to see that me and my girlfriend are alive and in tact. We are close to the jagged cliff face, and there is alot of seafoam, debris, bodies (alive and dead floating in the water). I suddenly find myself walking atop the cliff face with my GF. We are soaking wet, and bit cold. The weather has the after-storm feel. We find a building with a faux Tahitian style (like something you'd see in a tourist hotel), we walk inside and its dark and the floors are wet, it looks like a mall food court or a souvenir shop. I'm relieved to be alive and exhausted.There are other people sitting inside, some covered with blankets. We sit on the floor for a few seconds. Suddenly it dawns on me that we are alive and "able bodied"...it is our duty to do something. I rush outside, and down a small path on the cliff side to a beach. I tell my girlfriend to help as many people and I will meet her up later. My girlfriend jumps into the water and starts swimming to help people, she disappears. I am not worried about her though, I know she is a strong swimmer. I find a slightly chubby man in tourist attire (Hawaiian shirt, shoes, sandals) he is late 30s maybe early 40s, he is a stranger to me, he agrees to help though. He seems a bit apprehensive though on taking orders from me. I tell him not to worry, and I quickly rattle off some credentials of mine. I tell him about some of my military experience (USCG, USAF) and how I was police officer. (In reality this is only partial truth, as I exaggerated and left out the "whole" truth. While I was trained in all these things - the reality was I never had any "real" experience in this type of situation, but I wanted to gain his confidence). He seemed slightly impressed and then asked my age, in a tone of disbelief as if I was to young to have this experience. I told him my age, mid twenties. He responded by saying "you must get around", and I replied "I do". I then jumped into the water, and the water again very cool (almost comforting feeling). I found a floating body, I turned the body over. It was an older, obese gray haired man with a mustache. Suddenly a sinking feeling came over me, I realized many of the dead must be elderly, or the young. It was about this time I felt that my mother was on the island and she was probably dead. I had a since of loss and dread, but I tried to hide it, I knew I couldn't worry about it to much and I had to move on (there was still a bit of hope, but I wouldn't count on it). I also had a feeling of disappointment. The hawaiian shirted man, was still standing on the ground, he pointed next to me and said "there, this person is alive". I swam to them, it was a woman in long black gowns. She was passed out, but alive. I felt good, like we were making progress. I yelled to him "TRIAGE, WE HAVE TO USE TRIAGE HERE!". I knew we couldn't save everyone. The man threw me a surfboard, and I used it to float onto as we pulled the body out. Other people began joining in and started to bodies out. I found an industrial hangar on a dock. The doors were open and it was filled with rescue equipment, like it was an abandoned life guard post or something. My girlfriends brother was suddenly there, and he was helping me sort through equipment, suddenly a life guard came inside, he said there was so much devastation throughout the island that they couldn't help everyone. He appointed me in charge of the station, and dropped off even more equipment- jet skis, a truck, first aid equipment, and life vests. I felt a giant relief sweep over me, like I had received recognition and was making progress. I then woke up feeling mentally and physically like I had worked. It was very vivid and I immediately started telling my girlfriend about it.

About Me: I'm a 25 year old male. The past 5-7 years have been very difficult, I attended college which was very hard for (due to the workload and finances). I joined the Coast Guard Reserves for a year, and the Air Forces Reserves for another year to make money for school. I didn't really enjoy my experiences in either branch. In the same span of time, I lost both grandfathers to illness, and I lost my father to suicide. My mother also contracted breast cancer, but she successfully had it removed. Since I was a child I've wanted to work in Law Enforcement, and since 2008 I have actively been pursuing a career as a police officer, I even put myself through an academy. I was hired for brief stint at a small department, but was let go. Since then, I have graduated college and have found it hard to find another job as a police officer. The economy as well as my stint at another department have held me back from getting another police job. Mostly because future departments think I was fired for some sort of misconduct (but this is not true, it was just small country town and I didn't like it - I wanted to be a city cop and they recognized this, I still talk to my old department too). For the past two years, I have been across the nation and on an seemingly unending stream of rejections - but I still keep applying, its my dream. I live with my girlfriend of 8 years, we have a great relationship, she is supportive and successful in her own endeavors.

Sorry if my dream was to long. It was very detailed and I thought giving all the details would be beneficial to the interpretation. So what does all this mean?
