Third Edit: Dollar Store Blues

Dollar Store Blues

Crossing the threshold feels somnambulistic. I would change "somnambulistic" to "like sleep walking" - I think most people will feel nothing with somnambulistic, at least until they look at a dictionary. Plus, "sleep waking/in the cleaning aisle" could be a cool line break.
In the cleaning aisle,
she swears she sees an allegory an allegory for what? cleaning up her life? that would be more of a metaphor or a pun.
until she is distracted by a sale for expired taffy;
so sticky and sweet, yet barely fulfilling a need
she'd rather deny exists. nice.
She closes her eyes, allowing the fluorescent lights
to bath her like a cold shower. Nice, lots of sensations.
Eventually, she arrives at her purpose:
Is she there to buy beans or soup?
She pretends the decision hasn't already been made
like he husband's bed. her. 
Placing a finger against her lip,
she smells the soap she bought here a week ago.
Mechanically, she reaches for a can
and it sticks to her palm like a magnet.
Her hands smell of cheap metal as she approaches to pay. I like mechanically, magnet, metal - robotic.
The cashier smiles androgynously.
The cash register speaks,
the dream ends.

Nice, this person's life is so dull she dreams about the dollar store.
