Cover art for Wait lyrics by Alexi Murdoch

If you would have asked me 7 months ago , I would've agreed with that interpretation. But after I lost my love and best friend, I found that this song had much deeper meaning. In fact I listened to it several times a day to help say what I was feeling. I think overall, he's asking if I mess up here, in this life--do something stupid or something shameful,("if I stumble/fall") Will you still wait for me in the next life.
He also talks about dreaming about the sea and waking up feeling blue, cause he wishes he could dream of "you". You want to stay connected, even talk to the one you've lost. When you dream of that person, it's bittersweet, but you're gald you saw them again. And when you don't dream about them its upsetting...it definitely makes you blue.
