Lyric discussion by CatAtomic99 

I think this song is just about the desperation of modern life, and the way this man's sanity is hanging by a thread. Apparently it's starting to show externally as well, as no one hassles him when he goes through the picket line that day.

I think the monster and the Scottish lake are metaphors for his psychological state. Something primal is coming up from the depths. The 'shadow on the door' is a pretty suspenseful bit of imagery to end with, and I think it implies that something has broken, or at least changed in this man's mind.

It's also interesting to note that the man is always 'staring into the distance', and this monster is 'many miles away'. That's a big part of what makes me think the monster is a metaphor for his own mental state.
