Negative pressure is somewhat of a tricky topic and its larger effects in physics are debated. What it does to the human body, though, are undeniable.
Your prompt is NEGATIVE PRESSURE.
Oxygen expands
Your tissues start to rupture
Bubbles in your blood
Ok, so you wouldn’t decay to a skeleton, your blood would boil, organs would rupture, and then you’d be freeze dried, but try finding a picture of that.
Bag of bright bright blood, burst -
the sun glints on the crystals mounting
eye gel turned to twin diamonds
________
Careful not to confuse negative pressure in the cosmological sense, which may or may not be a facet of dark energy pushing the cosmos outward, with the thing we're talking about here which is simply regular pressure working as normal (though with very negative consequences for our squishy pressurised body).
• Daily pressure mounts,
Expectations press too close—
Who’s really to blame?
• Words twist and compress,
The weight of should-have-been’s there—
Pressure never stops.
• Silent stare cuts deep,
Expectations suffocate—
Fear, an unseen hand.
• Pressure to conform,
Air thick with everyone’s needs—
Self crushed into dust.
• Expectations press,
The weight of a thousand hopes—
Cracks in the mirror.
• Love squeezed too tightly,
Air forced from a fragile chest—
Affection’s cruel grip.
