This song is about a relationship. "Like walking into a dream, so unlike what you've seen, so unsure but it seems, ’cause we’ve been waiting for you, Fallen into this place, just giving you a small taste of your afterlife here so stay, you'll be back here soon anyway". At some points it's like heaven, and others it's like hell. Simple to figure out. And he is not sure if he's, so to speak, ready for it.
I do have to say, This is probally one of the easiest songs I've figured out the maning to, & before you disagree with me and start to yell at me because I'm "wrong". Maybe You should listen to the lyrics.
