@Cheladas Great interpretation, but other meaning could be about victim of a nuclear explosion. The lyrics are about victim's perspective after the death. Ofc, this song also could be associated with death or suicide.
I know this song... It plays when you love someone enough to let them completely inside… and they find the abyss. It looks just like their own. They pull away. They board up their windows, choose a new name. You delete their contact information, their photos, their emails. You never speak to them again. You still miss them. More, each day. They stay hidden. You can’t tell them not to worry. You can’t help them forget their fear, to move on, without you. Unless you disappear. Completely.
But yeah, when you lost the dearest things, when you lost her, when you nothing anymore for her (or when she tries to give that impression), it really feels like disappearing. Probably because you were judging yourself through her eyes
