When I wrote lyrics for my never to be released concept album because im fucking lazy i always tried to have two meanings to them.
1. Obviously to tell the story how I intended it, about a woman, who did some ritual for teh lulz, but ended up summoning the entity, who ended up "possessing" her after destroying her mentality. It was pretty straightforward, track 1 summoning instrumental, track 2 entity appears, track 3 entity does mindfuckery and tricks grill into killing her boy, track 4 chick goes from "oh no my love" to "oh shit gotta hide the body", track 5 guilt, track 6 mental torture until weak enough to make her obedient bitch
2. But lyrics were not that straightforward. Sure, they told a personal story of a random chick, but nothing stops you to interpet it as, i dont know, someone pondering about their past, feeling fear, guilt and eventually being overwhelmed by all of this.
When I tried going with very straightforward lyrics they were easy as fuck to make, but it sounded way to lame for me. It still probably is lame as fuck, but not instantly.
So I'd go with somewhat "deeper" lyrics.
