Verse 2-
                 Em
There's a devil in the corner, in candy apple red.

Dressed up like a fire, burning through my head.

I got a little closer, and offered her a drink.

Who took me to the graveyard, and we did the trick-or-treat.

Repeat Chorus

Bridge-
Em                                           C
Before I learned her name, we were already asleep.

When I woke up in my coffin, she was nowhere to be seen.
Em                             C          D
Was it all a dream, who can I believe?
Em                                         C     D
It can't be what it seems, it was only Halloween.

What does it all mean?

Repeat Chorus twice.
