At the end of this lone road I see a dark house And only from one window A spark is glowing in the night Oh, there's a feeling inside of me Preventing me from going I've built a prison to lock up my heart There's not a chance of breaking in I've built a prison to lock up my heart And I can't let anybody in With every step that I approach It's only getting harder for me But I made a promise long ago That I'll stop at nothing Still there's this feeling inside of me Preventing me from going Insistent voices inside my head Keeping my mind from roaming I've built a prison to lock up my heart There's not a chance of breaking in I've built a prison to lock up my heart And I can't let anybody in Anybody Not anybody in Anybody Not anybody in I've built a prison to lock up my heart There's not a chance of breaking in I've built a prison to lock up my heart And I can't let anybody in And I can't let anybody in And I can't let anybody in
