As far as I can tell, this song is in the key of F Major. And the chords are all 
Major unless otherwise noted.

F      Bb        C    F          Bb        C
When I close my eyes, I suddenly realize
Dm                  Am(1inv.)  E      Bb 
There's no place on earth, I'd rather be
F      Bb           C
Than lying, by your side

This pattern repeats throughout the rest of the song. If you think that there is 
an error, please feel free to email me to change it. By the way, the (1inv.) means 
first inversion, that the E is played in the bass, and the A and C are played in the treble.
