On a GCU - Only if I close my eyes

This could be

If I close my eyes tight enough 

and focus hard enough

A space ship

A vessel

A GCU

It could be

Attitude adjuster

or Sleeper Service

Or Peace makes plenty

or even Grey area (aka meat fucker)

with it’s inhabitants

of males females and the in-betweens 

travelling to other galaxy clouds

habitable planets 

orbitals

leaping from space to hyperspace 

this announcement could be 

of the great mind of the vessel

or it’s avatar

It really could be 

only if I close my eyes 

PS: I have discovered the Culture  , a post scarcity, semi- anarchist utopia consisting of various humanoid races and managed by very advanced artificial intelligences. The vessles have mind of their own and machines are considered persons. The Humanoid can regrow their body part , secrete custom drugs through organs implanted and change sex many many times . Finished my 3^rd book and I mostly read in the train.

If you can , try to read a few by Iain M Banks.
