Dream About Deep Ocean Submarine Mission

This dream was about

I was in charge of a mission where I had to lead a team in a submarine to go thousands of feet deep into the ocean, deeper than anyone has ever went. The first part of the dream was the mission it self, we entered a water cyclone tunnel and leviathans started attacking the submarine and dragging us down. They used sonic waves to try break up the submarine and I started to use sonic waves that I screamed to try counter the attack. Once we exited the tunnel the bigger leviathan had instructed us to dock at the moon pool so that we can talk. There was also another submarine there and I guess that someone else was here and could be someone we maybe looking for. I docked the submarine and before I left the submarine, the captain stopped me and informed me how terrified he was. I comfort him and told him not to worry, turn on the lights and everything will be fine and we hugged and I started to walk away and the dream faded into the second part of the dream showing how I assembled the team. In the beginning of this part I was getting a message and this couple started arguing, I needed both of them for the team and so I had to intervene. They had a weird relationship. He was an agent and she was a spy/assassin and they had love for each other but also hated each other and just liked making things hard. He was trying to convince her to listen to us, because I had convinced him earlier to join and he agreed. She looked me in the eye and ask what the mission was and what the risks were. I started to cry and I told her the truth, I told her "To be honest, I don't think I will be coming back, I will make sure everyone else does, but I can't speak for myself". She then came closer to comfort me and then she agreed and I stopped her and said "No, I don't think you should go anymore, I think you should stay or at least still help but stay on land", this she agreed too. After I left and joined everyone later that day to discuss the mission and everyone was skeptical about some of the details, especially the depth. The depth was nothing anyone has heard of and we weren't sure if the submarine would hold due to the pressure. The report stated that we had to go 2 million feet deep whis is about 380 miles. The captain was very vocal about his concerns but I informed him and everyone that another submarine didn't and everyone was shocked. After the meeting we decided to get preparations done and one of the main preparations was creating the entrance, we did this by the instructions that were given but this made everything more weird. To create the entrance we had to have a heavy set child break a hole through different layers of a specific spot and so we recruited a 10 year old boy who managed to get the job done. After majority of the preparations were made I had everyone go spend time with their families before the mission and so did I. While visiting my family, I got a call from my former boss, telling me that she called because I was on the promotional list and she was calling everyone on the list to invite them to come in because of a special the spa was having. I agreed that I would come in but I knew I may not attend because of the mission and my chance of not making it back. I also informed her that I wasn't sure if other former employees would make it. After talking to my former boss on the phone, I hung up and continued to spend time with my family.
