Dark Waters

[gedankespieler]

Heart capsized

no longer drifting

further away

swims reality

This is ambiguous because of the lack of punctuation. Reality swims further away? Somewhere in the distance, reality swims? Is reality no longer drifting? Or is it the heart that is drifting?
I'm not going to assume you did this deliberately, because the lack of punctuation seems consistent throughout, rather than being a stylistic choice for one set of images.

submerged

eyes blurred

limbs wavering

unclaimed depths enticing

Are they enticing? It seems to me as if the descent is reluctant, above all.

mindless pressure pulsing

in the mirror

of dark distortion

surrounding me

numbing pressure pulsing
through the dark distorted mirror
all around me

(too much emphasis is on the "surr" ins "surrounding", leaving the stanza unbalanced)

Heart capsized

No longer drifting.

further away

swims reality

You could change this to make the ending more satisfying, e.g. switch it up -

Heart capsized,
No longer drifting;
Reality swims
further afield.
