lots of lifeforms in the eigengrau sea.. 
      plankton... small glowy dots,       
 appearing, disappearing, getting eaten.. 
 eaten  by whom? more reluctant  buggers. 
 squids!  in  a  good mood  they'll  form 
 trails and weave  whole dreams in  front 
               of your eyes               
     sometimes there's a flowy slowy      
       pulsating yellow sensation...      
     translucent--- probably jellyfish    
  also urchins, feather stars, although   
 you  will need to adjust your perception 
             a bit for these.
