Bulbous Sanguine Corpus callosum

I tiptoe

Along the bridge between worlds of

Hemispheric delight

Will it carry me over

Rivers of hell?

This corpus callosum

Built with brittle Styx

Falls apart like a capsized vessel

I swim through the sanguine river

I find myself in

Lurching towards the bulbous shore

Of mind
