Animal Dreaming and Substantiation: A Potential Field in Science

Animal sleep is presented in various patterns like hibernation, nocturnal activity, and even napping! For example, penguins rarely sleep in case of abrupt attacks of predators. They sleep in standing positions for only a few minutes to provide security. In some occasions, penguins take naps in the ocean after a full meal. As this example demonstrates, the state of sleeping in animals is confirmed based on scientific research. The evidence of animal sleep is obvious, mainly characterized by temporary unconsciousness, non-responsiveness to external stimuli, and passivity in movement. Although animal sleeping is corroborated by these common symptoms, animal dreaming is a controversial issue in the scientific field. Many scholars are opposed …show more content…
After running in the maze, rats remembered and reconstructed the maze structure in their dreams. The fact was proven by the repetition of unique brain activity when the rat ran. Moreover, Hypocretin, a significant factor of sleep control, lacks in both human and mammals. Hypocretin refers to the neurotransmitter that regulates arousal and is less produced in the human brain. Lack of Hypocretin leads to Narcolepsy, a sleep disorder which exhibits sudden collapse. This disease is related to deep sleep, and slow-wave sleep also involves dreaming. For example, Narcolepsy is manifested mostly in dogs and mankind, this correlation shows that both species experience dreaming. Therefore, mammals which sleep relatively long and lack Hypocretin have a higher possibility to dream because dreaming is proportional to the amount of sleep. Next, the stage of REM and non-REM sleep appears in animal sleep as well. REM sleep is defined as the sleeping stage characterized by rapid eye movement. Firstly, most dreaming occurs during this fifth stage in mammals, and lasts up to an hour as sleep progresses. Conducted by a research in 1953, the recalling of dreaming is high after REM sleep, showing an average of about eighty percent (Aserinsky & Kleitman). As a result, mammals which experience REM sleep are expected to dream.
