Cover art for Shampain lyrics by Marina and the Diamonds

For those who are confused, her album version of the lyrics are:

Laid out dead Inside a lonely bed Trying to hide the hole inside my head

The lyrics on her site say Laid back in bed, but I believe that was her previous version, as she has changed lyrics in her songs for the album versions. And you can clearly hear that she does not say "Laid back in bed."

Another site said "laid dagger dead" but if you pay attention closely there isn't enough syllables in what she sings for that to be correct. The way she pronounces her words it's sometimes really hard to tell what she is saying.

But your correction makes a lot more sense. Though it makes it sound like a suicide song. dose "Hole inside my head" refers to a bullet wound?

Consistency is questionable with that interpretation.

yes, but if you see her music video it involved being girls as zombies who died at a party. So I believe with talking about angels and such there is a death theme there and yes the hole in the head might be a bullet hole.

And you can also be dead without being dead of course, like how people joking refer to being passed out on alcohol and such.
