What do red doors in movies mean?

and when the dead return to us
why do they always come in groups?
except when you came it was quite alone

fires in rome
burned down my childhood home
i hope they play the fiddle at my funeral too

death can seem such a sweet release
but none of us truly know
recycle my heart it is biodegradable

we cannot stop the snows from melting
as much as their coming too
but we can celebrate all with joy

now these stairs some call life
will you walk down with me?
'cause there's a dragon in the basement

monsters down the hallway
and who knows what is outside the house
but i will open up my window

in the middle of the night
and welcome you to my heart
we may not live but die in the dark

so if you see me walking down the road
with death at my side just let it go
this is how it is supposed to be
