dum haec me stupente (Sat 137)

[cinefactus]

Dum haec mē stupente in lectulō sedet ānserisque fātum complōrat

I a little unclear about the grammar here. Is there an implied dicit or fit after haec?

 

[AoM]

Could haec be nominative?

 

[cinefactus]

Could haec be nominative?

Facepalm
Of course, thanks
