Popular Theories On Consciousness

Not all NDEs are positive - some can be frightening, with intense terror, anguish, loneliness, and despair. Distressing NDEs are underreported because of shame, social stigma, and pressure to conform to the positive NDEs.

A close encounter with death reminds us of the fragility of life and can reveal the layers of psychological suppression that prevents us from these uncomfortable thoughts.

A 2017 study found that NDEs were recalled with greater clarity and detail than either real or imagined situations were. In other words, NDEs were remembered as being more real than life itself.

NDEs are no more likely to occur in devout believers than in secular or nonpracticing subjects.

The synchrony between the brain activity of a performer and his audience shows insights into the nature of musical exchanges: we dance and feel the same emotions together, and our neurons fire together as well. This is especially true when it comes to the more popular performances.

Synchronous brain activity was localized in the left hemisphere of the brain (temporal-parietal junction). This area is important for empathy, the understanding of others’ thoughts and intentions, and verbal working memory used for expressing thought.

The right brain hemisphere is most often associated with the interpretation of musical melody.

In the right hemisphere, synchronization is localized to areas involved in recognizing musical structure and pattern (the inferior frontal cortex) and interpersonal understanding (the inferior frontal and postcentral cortices).

According to a 2004 research, the sense of smell is a complicated process.

• The olfactory receptor cells send a neuron signal to a part of our brain which is called the olfactory bulb.
• This multistep process which involves over a thousand genes and the nerves connect to the amygdala of the brain, the area responsible for processing emotions.
• It also connects to the memory and cognition area called the hippocampus, forming the association.

Scientists claim a brain glitch blurs the wakefulness and Rapid Eye Movement (REM) modes of sleep, making the dreams come out in the real world, creating a hallucination.

To prevent you from acting out these dreams, the brain paralyses your body. Sometimes this mechanism fails and you see your dream in augmented reality in the real world.

The Egyptians referred to sleep paralysis as something caused by a ‘Jinn’, which terrorizes and even kills the victims. Italians refer to this figure as Pandafeche, a giant cat.

South Africans interpret this as small creatures known as tokoloshe, who perform black magic, while in Turkey the creature has another name, the Karabasan.

• The non-mirror-style self. We are used to seeing ourselves mirror-style. When you move your left hand, it will always be flipped when you view yourself in a mirror. On Zoom, you lift your left hand, and the opposite side moves on Zoom. This feels disorientating. Thankfully, Zoom has fixed this.
• The perfect self-contingency detection. When you lift your hand in front of a mirror, there is no lag in the image. Now you feel your arm stir and see it move a few seconds later. No wonder we stare at ourselves.
• Glitchy wifi magnifies the slight asynchrony. The response delay disrupts your feeling of connection with another person. You can't read them, and they can't read you.
• A documented phenomenon is that we accurately recognize neutral expressions on other faces, but we misidentify our own expressions. We see our own expression as unfavorable most of the time.

As the human life span increases to span centuries, the planetary environment, along with the collaboration and cooperation among nations would come to the forefront, as hostile people and chronic pollution are extremely dangerous in the long run.

While our survival would still not be a guarantee, there will be a new challenge of overpopulation, which could be moderated by sending people into space to colonize other places, and by limiting the birth rate.

As inter-galaxy travel becomes a reality, there could be many spaceships which would be able to take us to nearby habitable solar systems, setting up for new adventures, challenges and a completely radical lifestyle.

The changes in Earth’s biosphere could also be a concern, as new technologies and constant harvesting of resources (like deforestation) can lead to dangerous environmental changes.

• People who rock while sleeping tend to be less disturbed during the night and maintain their deep sleep longer.
• The memory function improves by a factor of three, according to a study.
• Rocking synchronizes the brainwaves in the ‘thalamocortical’ networks of the brain, helping both sleep and memory consolidation while improving one’s mood.

• Women and adolescents are quick to feel the negative effects of shame, and dive into low self-esteem and depression at a much faster rate than men.
• Young people have a stronger ‘pull’ towards any kind of emotion, including shame, which is the reason for them being susceptible to severe depression.
• The propensity of shame decreases as we grow older, but elders again start to feel ashamed just as a young person, as they get self-conscious of their actions, appearance and bodily decline.

• Guilt is related to shame but is easier to rectify, as we focus our attention on the other person and apologize, accepting responsibility.
• Shame is an inward emotion that makes us view our entire self in a bad light, with us getting punished by our conscience.
• Guilt is actually a positive emotion, showing our empathy and encouraging us to reverse the harm that we may have done.

Humans are different from animals in that we don't sense time only as passing. We dice time into units or think of time to go beyond our lifespan, such as millennia. We rely on time concepts that allow us to make plans, follow recipes, and discuss possible futures.

Recent research suggests that across all cultures, the concept of time depends on metaphor, known as a conceptual metaphor. We build our understanding of duration and sequences of events out of familiar spatial ideas such as size, movement, and location.

But the "time is like space" metaphor takes on very different forms from one culture to the next.
