I made the chords for piano, my instrument. I start of with the chords later, I 
begin with the simple intro. I play that with the notes:

C#, C#+1, Ab, F
(then again C#+1, G#, F another 4 times holding the first C#)
F#, F#+1, C#+1, Bb
(then again F#+1, C#+1, A# another 4 times holding the first F#)
And with the "When I was alone, is there a ghost in my house?" part,
I played G#, G#+1, D#+1, C. And then again de last 3, you know it.
And by the time we got to "My house..." I'd switch to the chords.
Which are down below! I hope I'm right, not quite sure, but still, hope you can do 
something with them! Good luck!
