Do Jellyfish Dream if They Sleep, And, Two Haiku

I am fascinated by jellyfish. And apparently they sleep. Does this mean they dream?

Deep sleep: Even jellyfish need their slumber: Cassiopea jellyfish live in clear, shallow, tropical waters of the Pacific and western Atlantic oceans, eating plankton. Measuring about 1-2 inches (2.5-5 cm) in diameter, they are dubbed the “upside-down jellyfish” because they lie on the seafloor inverted in the water with their tentacles upward.

Through lab experiments, the researchers determined Cassiopea met three important sleep criteria: periods of decreased activity known as behavioral quiescence; a decreased response to stimuli; and an increased sleep drive after being sleep deprived. (Reuters.com)


Two jellyfish haiku I wrote not long ago:



a jellyfish sky
clouds pinked by the setting sun
in electric blue


But, more to the point:



the jellyfish, soft
talking about consciousness
white-pink minds, floating
