Dream About Deserted Resort And Impending Disaster

I was out exploring somewhere- it looked like a resort in Hawaii or something- and it was completely deserted. There was no one out there with me, which I thought was odd and a bit ominous but kinda cool at the same time. I could hear the birds chirping and watch the sunset in silence. Then I started to get this feeling of dread and I looked out across the sea and started to see this fleet of ships in the distance headed my way. I went inside, and it was set up like a war room and there were a few important looking people standing around either talking on the phone or to each other in hushed tones. I felt like a child walking in there, even though I was grown and knew I was supposed to be there. It felt like everyone was looking down on me. Like they thought I wasn’t supposed to be there, but I knew I was. I walked to the person in charge, someone I felt I knew for a really long time, and she looked at me like an old friend but when she saw my face and how serious it was she asked what is it, so I told her. That set off a cascade in the room with people starting to call other people and phones ringing and the news turning on and her face hardening. She turned to her advisor and I walked out of the room but remained in the building. The scene changed to me being with a group of people, possibly at the same resort? But we were out exploring the island and we had jet skis and whatnot. We knew it was dangerous, but we still had time to blow off some steam before we had to get serious and buckle down. So we went swimming and were having a good time, but I think we lost track of time because a group of agents or army people came to get us while we were still out having fun and the mood changed quickly. We had to gather up fast, but they also warned us the water we were in had creatures in it that could and would hurt us if they grabbed us, but we needed to get samples or something for scientific purposes. I was back on the ship because I was tired/leading the research team, but my brother was still out there. I was trying to get him to hurry up but he was too fascinated with being the hero and/or seeing one of these creatures up close (I think). But we finally left the area and got back to the base house, which is a house I had been in before (I think in another dream). All the blue chairs from high school were lined up looking at a tv like a presentation was going to happen and I was getting nervous. It was like the world was about to end and we had to watch a way to survive- which is exactly what it was. Everyone started prepping and I took the back stairs to my favorite hide out to process and think through what was going on. Then I woke up.
