How Memories Fade

[Philatone]

hello granny! wanted to share some thoughts

Yesterdays slip away too fast,
escape my desperate, feeble grasp.
the past fades into misty clouds ..I think the cadence would flow better with just "to" instead of "into". overall, I like the image, but imagining the past as a bunch of clouds , while fitting, does make me long for something more unexpected
elusive, transitory, lost in time...I think this line could be stronger if it just ended on "lost," removing the "in time". it would focus entirely on the pattern of the adjectives
Quick, bright, flashes
butterfly around ..like how you made butterfly a verb! creative and perfect
settling and fluttering
as they touch my mind.
Too brief...ok, here I think you could show rather than tell, maybe describing how the flashes scurry away as quickly as they came. this line has so much potential

Turned to dust and ashes
leaving a gulf of emptiness, vast and wide...not sure you need "of emptiness"
where stored-up memories ..these last two lines gave me the impression of memories being personified, resting in a retirement home or some attic. I think using "reside" in the next line is great! to play on "reside" and "people," you could switch "stored-up" memories to something that applies more to human nature--maybe even something like "retired memories". just an idea that came to me; I do like this close regardless.
should reside.

not sure if my suggestions came across as clearly as I would have liked, but it was an enjoyable read, granny.
