Dream About Tidal Wave Hawaii Sea Island Disappearance

I had a dream I was living on one of the islands of Hawaii. We (G and I) lived kind of close to the ocean. One day I looked out the sliding glass door and saw this huge tidal wave coming to shore. Before the wave hit I tried to reinforce the sliding door and lock it. That protected the us from drifting away in the current. When the water receded, I walked outside to speak with the neighbors and see if they needed help. While I was helping this young child the water started to receded again. So I yelled for everyone to get back into their homes for shelter. When the next wave hit and receded a beautiful Polynesian island appeared from the mist of the water. There were red and green bushes and flowers all over the island. It looked like it was protected by some kind of magical force. I had a message from someone that said this wasn’t over. Then the island disappeared. I was to save more people. So I went to the island Walmart and told everyone to get inside. Waylon was the store manager there and I told him what was going on. This Walmart was more inland so they didn’t know what was going on where I lived. G, Waylon and I started to get more people into the Walmart to protect them. As I was getting closer and closer to shut the doors down, I started to lose my voice. I asked one of the lady’s to page over the pa what was going on and that we were closing the doors. Soon there was one side door open and I was trying to get as many people in as I could. Some didn’t want to come inside until they saw the giant tidal wave in the distance. When they saw that they were crowding to get in. Finally everyone that I saw was inside or somewhere safe, so I closed the door just in time for the tidal wave to hit. Then I woke up.
