Lyric discussion by vchamberlain 

Cover art for She Screamed lyrics by Ultra Vivid Scene

The original album didn't come with a lyrics sheet, & I'm not sure where revontulet got these lyrics, but I've always heard the lines:

& so she ate half of that Now she can see in the dark

As:

& so she ate half a light Now she can see in the dark

It makes a little more sense - in the song's sexually perverse, drug-addled world, anyway.

@vchamberlain This was the lyric I was checking on too. I was hearing it the same way as you until today with headphones cranked. I think the OP is correct, but I like both hearings.
