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.
