Dreams

Dreams are stories and images that our minds create while we sleep. They can be entertaining, fun, romantic, disturbing, frightening, and sometimes bizarre. They are an enduring source of mystery for scientists and psychological doctors.

Are dreams merely part of the sleep cycle, or do they serve some other purpose?
Possible explanations include:
• representing unconscious desires and wishes 
• interpreting random signals from the brain and body during sleep.
• consolidating and processing information gathered during the day.
• working as a form of psychotherapy.
Dreams are a universal human experience that can be described as a state of consciousness characterized by sensory, cognitive and emotional occurrences during sleep. The dreamer has reduced Trusted Source control over the content, visual images and activation of the memory.

    There is no cognitive state Trusted Source that has been as extensively studied and yet as frequently misunderstood as dreaming. There are significant differences between the neuroscientific and psychoanalytic approaches to dream analysis.

     Neuroscientists are interested in Trusted Source the structures involved in dream production, dream organization, and narratability. However, psychoanalysis concentrates on the meaning of dreams and placing them in the context of relationships in the history of the dreamer.
    
    Our most vivid dreams happen during rapid eye movement (REM) sleep, which happens in short episodes throughout the night about 90 to 120 minutes apart. You’re more likely to remember your dreams on weekends or days when you sleep in because each episode of REM sleep is longer than the last. Most of your muscles become paralyzed during REM sleep to prevent you from acting out your dreams.
We may not remember dreaming, but everyone is thought to dream between 3 and 6 times per night. It is thought that each dream lasts between 5 to 20 minutes.
Around 95 percent of dreams are forgotten by the time a person gets out of bed. Dreaming can help you learn and develop long-term memories. Blind people dream more with other sensory components compared with sighted people.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

The Chemical Lake

 Spotted Lake or Lake khiluk in Canada is richly concentrated with various minerals. It contains dense deposits of magnesium sulfate, calcium, and sodium sulfates. It also contains high concentrations of eight other minerals and lower amounts of silver and titanium. Most of the water in the lake evaporates over the summer, revealing colorful mineral deposits. Large ‘spots’ on the lake appear and are colored according to the mineral composition and seasonal amount of precipitation. Magnesium sulfate, which crystallizes in the summer, is a major contributor to spot color.  Originally known to the First Nations of the Okanagan Valley (Native American Tribe) as Khiluk, Spotted Lake was for centuries and remains revered as a sacred site thought to provide therapeutic waters. It is the most mineralized lake in the world. Each spot holds a different cure due to the unique chemical content found within each puddle. Lake Khiluk is considered a saline endorheic alkali lake. The Okanag...

Why is the Pacific Ocean shrinking and the Atlantic Ocean is getting wider?

Twenty million years ago there was no Atlantic Ocean. But then, thanks to plate tectonics, the South American and North American continents were separated by a rift valley that eventually turned into the Atlantic Ocean. The complementary shapes of the South American and African continents have long been noticed, but it wasn't until the 1960s that the theory of plate tectonics became accepted as the explanation. These days, the Atlantic Ocean is growing at a rate of five centimetres per year, as new sea floor is created by volcanic activity along its mid-ocean ridge.        On the other hand, the much older Pacific Ocean is currently estimated to be shrinking by two to three centimetres each year. Again, this comes down to plate tectonics because the Pacific Ocean has subduction zones on three sides - where the Pacific plate submerges beneath other plates.  Since there are very few subduction zones in the Atlantic, Indian and Arctic oceans...
