Play along to the song a few times and the time signature makes a lot more sense.

[Verse 1] 7/8
Bm Bb Bm Bb G F#
All that I know's within the walls of this room where there's a window
G F#
Roughly boarded up
Bm Bb Bm Bb G F#
It's true the gaps are patched but even through the tiny cracks, I feel the wind blow
G F# Bm
I see a light it's strange as you
[Chorus] 4/4
Bb Bm
And there's nothing I can say
Bb G
There's no way I can prove
F# G
That there's a place
F#
Beyond this room
Bm Bb Bm
But still, there's something in the way
Bb G
The light comes shining through
F# G
And in the way
F#
The curtains move
Bm Bb Bm Bb
G F# G F#
[Verse 2] 7/8
Bm Bb Bm
Late in the night I lay awake
Bb G F#
My eyes fixed on the window
G F#
Swing my ears until
Bm
I thought
Bb Bm
That I might have heard a song
Bb G F#
Somehow hiding in the soft glow
G F# Bm
All this time, and never knew
[Chorus] 4/4
Bb Bm
And there's nothing I can say
Bb G
There's no way I can prove
F# G
That there's a place
F#
Beyond this room
Bm Bb Bm
But still, there's something in the way
Bb G
The light comes shining through
F# G
And in the way
F#
The curtains move
[Bridge] 4/4
G Em
I found a note scratched in the wall
Bm
In a pained and earnest scrawl
A G
The hand I recognized was somehow mine already slight with dread
Em
There's no wind and there's no light
C
There's no song in here at night
There's nowhere to hide, be terrified
Bm
It's all inside your head
[Solo]
Bb Bm Bb G F# G F#
[Outro] 4/4
Bm Bb Bm
But still, there's something in the way
Bb G
The light comes shining through
F# G
And in the way
F# D
The curtains move
