Do Fish Sleep ?

Sleep, on my mind, in my mind, will my mind ever find, the sleep it is loosing? 

 
I lay down to read my boy a book, my eyes feel like they have an anchor securing them into the sand. He insists I finish his Super Hero story. 
Tiredness affects your tolerance. A baby whom needs to be held and a three year old who needs everything to be just right. His socks to be straight, his hands to be clean, his honey not to be mixed in, no red in his food, his big bad wolf T-Shirt to be washed and more costume changes than Beyonce on a world tour before we can make it out the door.
Sleep regenerates us, allows us to process all that we have experienced in our busy day. Sleep occurs in our brain, our ability to react to stimuli shuts down, all voluntary muscle movement ceases. Our brain enters phases of lighter sleep to deeper sleep, back to lighter sleep throughout the night. We need sleep to grow and repair our weary bodies.

Do fish sleep?

The parrotfish found off the Indian Ocean makes itself a mucous sleeping bag and rests upon the seafloor. This mucous bag protects it from parasites while the fish recouperates from its day munching on limestone coral. Does he Sleep?

The definition of sleep is used loosely when it comes to most fish.  Fish do not have the brain biology to enter the phases and shutdown of deep sleep us mammals experience. However in a way, these fish do actually sleep as their reactions to stimuli and amount of activity reduces. Some fish like the Parrotfish are known to “sleep” in this way, some like the Sharks must continue to keep moving in the water.

Ever since I was a child I have been fascinated by sleep. I even had fleeting thoughts of becoming a sleep scientist. It was the psychology of sleep that fascinated me, where do our minds take us when we rest at night. A fragmented world from a Salvador Dali painting that helps us to form memories and make sense of our lives.
I have had many a dream diary, containing surreal visions I will never forget. Tsunamis, visits from my grandmothers passed, storms, dolphins and nightmares of being chased. Dreams or hallucinations of a presence in the room pressing down on my chest so hard I could not breath. Dreams of holding babies, taking care of them, loosing them.
These days I am lucky to get sleep. 
I have lost my ability to always remember my dreams, my rests always broken to nurture my young. 
It will return this dreaming ability, I know.
Do you remember your dreams?
Can you sleep?
Do you love sleep?

One theory suggests that during sleep, sensory information (predominantly visual) gathered during the day is processed to form memories. Fishes that swim constantly in blue oceanic waters receive little ‘unusual’ visual input and require less ‘memory-processing time’ and thus need no sleep. This is supported by studies on several species of blind fishes that live in caves. These sightless fishes do not sleep. – See more at: http://australianmuseum.net.au/Do-Fishes-Sleep/#sthash.FE7pskQF.dpuf
