I love this song. It seems to me that it's about a trip to some infamous battlefield. "We criticized the oldest skulls we found in corners everywhere," "And all the rocks we saw were dashed with young men's spines." So his companion is having dreams of ghosts and holding her breath when passing the cemetery. That's why he whispers "I had to come," as in, "I had to come to this place."
