A free verse poem

White-knuckle grip
on a tube held to my eye.
Peripheral darkness,
vision now constrained
within a helter-skelter tunnel
heading towards
a pool of rainbow light.
The hypnotic, rotating epicentre
screws-in my armless body;
no braking hand can be used
against the slippery walls
I’m falling between.
Triangular panes of
Primary colour…
