To me, this is about someone who was in love, but they did something self destructive and ruined it, stated in the lines:
And of the few things that I am certain,
I'm the captain of my burden.
Which mean he is most likely the cause of the problem. The first verses are just memories and plans they made. Then the chorus comes in with a lot of imagery depicting a storm, which could mean their plans were ruined. The last line, Atlantis is my only dream tonight, probably means that through the storm the person is hoping to find some sort of paradise at the end of it, but the song doesn't really have a solid conclusion so I would say its unknown if they find it.
I got all this from a personal experience I've been through, so you all might not see it the same way as me.
