This line is an addition to the previous line, giving it a grotesque meaning and adding a sudden severity to the song.
Alone, this line gives hints of the homoerotic, a bed disshelved from a romantic encounter.
However, when coupled with the previous line, it can be seen that Sufjan wrote it to say:

I’m in the red impressions of the unmade bed
You cradled close to me, close to my ear.

This paints an incredibly gory and disturbing picture, the obsessed lover cuddling with a recently killed victim, blood seeping into the crevasses in the bed, and settling into red impressions.
The narrator has killed his lover in an act of greed and jealousy, and his instability has caused him to come to the conclusion that the only way to keep his lover was to kill him.
This brings the song to a dire ending, and colludes with the theme of corruption and greed in love in the song. .

To be ‘In the red’ is a business expression meaning to be in debt to someone.
It comes from old business practise, when a business would account for their debt in red ink.

The narrator says he’s in debt to the lover, and acts as though he’s repentant and just looking for forgiveness.
However, ‘in the red’ takes a more grotesque meaning when paired with the next line. .

He continues to kiss up to the subject, saying that he isn’t trouble anymore. .

The narrator is being complimentary, trying to get back on his good side.
This comes from royal tradition, where someone will kiss the king or queen’s feet as a sign of respect.
He is saying that he’s going to treat the lover as a king, to regain his approval. .

Between verses, an amount of time seems to have passed, and there seems to have been a confrontation between the two.
The narrator seems regretful and loving again, and seems to be again vying for the subject’s attention.
He speaks of the fact that his obsessiveness is getting better, and it seems like he believes this will be enough to get the subject back. .

This is a more urgent rendering of the greed and jealousy he feels, and he seems to be less complacent with the situation in these lines.
This shows a transition between a loving longing and a crazed fanaticalness. .

This line can be interpreted in many ways, but it is most likely a stream of consciousness detailing the narrator’s jumbled thoughts, and his obsessions.
The character seems to be fawning over the lover’s back, and making a physically intimate connection, but he punctuates this with imagery of violence, and the thoughts of stabbing him.

This can be seen as another facet of jealousy, and his mixed emotions. The subject’s beauty seems to be a stem of the jealousy, and it motivates him into murderous thoughts.
This imagery may be a symbolism of the maniacal thoughts that his love, greed, and jealousy have driven him to, and it is another clue pointing towards the narrator’s mental instability. .

The narrator starts with disturbing imagery.
In between the eyes is a common target for fatal attacks, as any medium-deep puncture to that area results in brain penetration and usually irreversable damage.

It can be assumed that the narrator is beginning to make threats towards the lover, becoming more and more obsessive towards the subject of the song.
His obsession is becoming dangerous and maniacal, but it can be noted he still hasn’t acted on his words.

This line brings in the theme of jealousy again.
This is a transition from his love of the subject, to his jealousy and greed towards him.
Instead of leaving him be, he begins to be obsessive and greedy, wanting the lover all to himself, which is probably a selfish impossibility. .

The character reminisces of a time in the past where they had been close, setting out on a trip together.
It is revealed to the listener that the lover is also a man, adding another layer of complication onto the already convoluted theme.
The hairy chest is a symbol of masculinity, and the narrator can be seen as again going back to his love interest, recalling how similar they were, and how they acted as one, not separately. .
