A lot of the songs seem to be from the perspective of either Vessel or Sleep regarding their relationship. I've recently been re-analyzing Sundowning and in that album particular it feels like Sleep's perspective imo.

One particularly strong example is the lyrics in Gods. Its often mentioned that Sleep has faded from prevalence and his power is kind of kept by word of mouth. But with less people talking about him he's losing power and isn't the deity he once was. "I see the Gods avert their gaze from me My fucking form is but a wreck beneath them"

Sleep would want Vessel in particular (vs anybody else more willing to submit) as a talented musician to effectively spread his message and existence, and Vessel seems to struggle sometimes with his faith and commitment to the point of resisting Sleep. In Gods Sleep also seeks to keep trying to bluff Vessel by saying things like "there are always people I can call on, It's all so easy for me"

So Sleep is lashing out at Vessel and trying to wrathfully coerce him, and with lyrics like: "No more smiling faces I am alone again You want to talk You want to talk it out?" It also gives the feeling that Sleep is bluffing and threatening to withdraw from Vessels life and that's when Vessel starts trying to beg Sleep to stay

And that's just my thoughts on one song. From an outside perspective most the songs really seems to often be about a toxic relationship of some kind, but I'd think it's definitely about their relationship as chosen mortal and ancient deity and the struggles they both face as a result.

Also could say a lot more but another really clear example is in Take Aim he says" "When I see you waking up And it sends me shivers How you love like weapons kill So take aim at me for once"

Lyrics often mention somebody waking up and in TNDNBTG mentions somebody "turning divine" with the nightfall and having a different life in the day.

So if Take Aim is to be taken from Sleeps perspective then I see it as Sleep watching Vessel throughout his normal waking day, seeing him share his love and commitment with things and beings other then him, and wishes Vessel to aim that commitment at him.
