Regular Swimming and Lots of Sleep

Such a fascination for finding activities
Statistically likely to extend quality life
You have, Grandma. In this world,

Everything’s similar to some other things,
Which is why memory works at all,
And what it works for is more predictions.

Illuminatory hallucinations, predictions,
Based on imagination, based on
Memories, themselves hallucinations

Of sorts from crushed experiences. Absent
Sensory checks, memories shapeshift
Into those changelings known as dreams.

You might notice, when you sleep less,
You dream more, and more vividly—
Phosphorescent memories surfacing

To mate and feed in the black waves,
Growing more concentrated and turbulent
As your nights shorten. Nothing like sleep.
