Dream of sudden destruction

In the early morning hours of 08/24, I had a very vivid dream and I believe I'm supposed to share it:

I had a dream last night that I was at a big ocean beach and we were all just having fun and morals had gotten pretty bad. There was no separation between men's and women's showers and changing rooms. In the dream, there was a girl who was wearing lingerie type underwear and proudly walking around the unisex changing room while a lot of people were freely ogling and complementing her.
At one point she walked into the same shower stall her mom and boyfriend were showering in and the boyfriend started ogling her. Even though the girl was dressed inappropriately in front of the mom's boyfriend, right there in the shower with them, the mom just started getting mad at the boyfriend and accusing him of being more attracted to her daughter than her. He didn't seem that concerned she was mad and just laughed and wandered away.
She didn't talk to her daughter about decency or anything. She just carried on with her like they were best friends.
In the next part of the dream, there was a young girl who had gone missing with her siblings for some time and her mom had found them recently.
The mom took them all to this big beach to celebrate their return.
I walked by them at the beach and recognized the little girl from the local news. I was excited to see her home and reunited with her mom.
I congratulated them all and as we were all standing around in a big, fancy, glass, dome shaped building visiting (it even had a glass roof), I looked past them, out this big glass window of the fancy building we were in, towards the ocean beach.
It had very suddenly gone from a sunny, nice day, to a windy storm with volatile choppy waves.
There were a bunch of other people in this big building too. Maybe like a big hotel or airport?
I pointed the sudden storm out to the family I was talking to and then, out of nowhere, an incredibly huge tidal wave that was even taller than the huge glass building we were all in overshadowed the entire building, towering over it and we all panicked as we knew it was going to come crashing down, full force on us and there wasn't enough time to even get out of the building!
We all freaked out, started screaming and some people were yelling for everyone to run away from the sides of the building where the windows were and pile up in the middle of the building and hunker down, bracing ourselves and covering our heads, similar to an earthquake/bomb drill.
This all happened in a fraction of a second, then the wave came crashing down upon us, shattering through the glass ceiling and side windows.
The force of it caused glass to go flying in all directions at us all!
We held our breaths, closed our eyes, and just tried to brace ourselves as this wave came crashing down upon us, full force! There was another couple violent waves that crashed down upon us and the force of them finally forced us through the front glass window of the building, as shattered glass was swirling past our faces. We just kept holding our breath, covering our faces, and just trying to survive.
Once we had been forced through the glass wall of the building, toward the land side, we all did our best to just get on our feet and start running towards the dry land, opposite the beach direction.
We were all just running and as we got to the regular land, we noticed that there were like military type officers set up all along either side of the path we were running on.
They seemed to be there to try and help the victims and control the chaos from the disaster but I quickly noticed they were carefully watching the people and were actually there to subdue and keep control of the masses that were going by and if any of the masses looked like they were aware of the soldiers or became suspicious, they would stealthily shoot that person, making it look like an accident or that they got in the way and became collateral damage.
The interesting thing is when they shot these individuals, they didn't kill them. The effect the shot had on the person was more of an amnesiac one.
They almost just fell asleep, forgot what had just happened, and became like the rest of the naive masses that were rushing by.
As I was walking by, one of the soldiers warned me I was getting in the way and that, "this is going to hurt a little.." and shot me in the back with a red mark. It stung a little and I started feeling sleepy and forgetting what had just happened to us all but then I realized what was happening and purposed in my heart to stay awake and remember what had just happened to us all.
So, I went along with the masses, looking like I was unaware as well, but secretly retaining my awareness and memories of the recent disaster.
About this tidal wave in my dream:
This is not the first, second, or even third dream I've had about a giant tidal wave! In the past, it's always taken place off an island of Hawaii, and though I'm usually in a tall hotel building overlooking the ocean, the wave is still tall enough to overtake the building all the way up to the floor I'm in. Which is always a high floor.
In this last dream, as we were being forced through the glass onto the land by the tidal wave, I remembered all the other dreams I had about this happening over the past years and realized all those warning dreams had just actually happened. I started to lament not sharing the dreams earlier and warning the people of what was going to happen before it was too late. But it was too late by the time I realized; the destruction had already come and the damage was done.
