Grief also tends to increase the chances of a ghostly encounter. Psychologists say it might be a way for the mind to process and deal with loss. Usually, the person they see is a comforting figure who appears serene. Another ghost-inducing phenomenon is called infrasound. This is a vibration that occurs below our normal range of hearing. Certain machinery like engines , whales, and extreme weather can all cause infrasound. Some studies suggest that it can result in symptoms including feelings of depression, the chills, and the sneaking suspicion that someone is watching you.
According to Hayden Planetarium director and astrophysicist Neil deGrasse Tyson, infrasound at 18 Hz vibrates at such a rate that the eye can pick it up, which might cause visual hallucinations. So if you or someone you know claims to have seen a ghost, believe them. But also, look for what evidence or phenomenon might be behind the sighting. You could end up finding a faulty lightbulb was the culprit all along. Which of today's technologies will shape tomorrow's world? A new report compiled by the World Economic Forum reveals some of the breakthrough innovations that are expected to radically impact the global social and economic order.
Making the list involves more than promising major benefits to the world. The emerging technologies must positively disrupt the existing order, be attractive to investors and researchers, and expect to achieve considerable scale within the coming 5 years. Biodegradable plastic offers a solution, but lacks the strength of conventional materials. A breakthrough idea promotes the circular economy by using cellulose or lignin from plant waste, which increases material strength without using crops that could otherwise be used for food.
Today's robots can recognise voices, faces and emotions, interpret speech patterns and gestures, and even make eye contact. Droid friends and assistants are becoming part of everyday life, and are being used increasingly to care of the elderly, educate children and undertake all sorts of tasks in between.
Making the lenses used by mobile phones, computers and other electronic devices smaller has been beyond the capabilities of traditional glass cutting and glass curving techniques. But advances in physics have led to miniaturised, lighter alternatives to established lenses, called metalenses. These tiny, thin, flat lenses could replace existing bulky glass lenses and allow further miniaturization in sensors and medical imaging devices. Unlike conventional proteins, they lack a rigid structure so change shape, making them difficult to treat.
Now scientists have found a way to prevent their shape-shifting long enough for treatment to take effect, offering new possibilities for patients. Recent improvements in fertilizers have focused on their ability to slowly release nutrients when needed. However, they still contain ammonia, urea and potash which damage the environment. New fertilizers use more ecologically friendly sources of nitrogen, and microorganisms that improve take-up by plants.
Imagine a video conference where you not only feel like you're in the same room as the other attendees, you can actually feel one another's touch. A mix of Augmented Reality AR , Virtual Reality AR , 5G networks and advanced sensors, mean business people in different locations can physically exchange handshakes, and medical practitioners are able to work remotely with patients as though they are in the same room. About million people eat contaminated food each year and it's essential to locate the source of an outbreak immediately.
What used to take days or even weeks to trace can now be tracked in minutes, using blockchain technology to monitor every step of a food item's progress through the supply chain. Meanwhile, sensors in packaging can indicate when food is about to spoil, reducing the need to waste whole batches once an expiry date is reached.
Although nuclear power emits no carbon dioxide, reactors come with a safety risk that fuel rods can overheat and, when mixed with water, produce hydrogen, which can then explode. But new fuels are emerging that are much less likely to overheat, and if they do, will produce little or no hydrogen. These new configurations can replace existing fuel rods with little modification. Our data storage systems use a lot of energy and can't keep up with the vast - and ever-increasing - quantities of data we produce. In less than a century they are set to reach capacity.

And for the record, if you spook easily, I recommended reading these with the lights on. I've had my own unexplained experiences with Ouija boards, so this allegedly true story sent straight-up chills down my spine. According to the story, a group of high school kids met up around Halloween to play with a Ouija board and see if it would actually work. Unfortunately, it worked too well, and almost everyone involved apparently ended up having some deeply disturbing and in some cases, near-deadly experiences that are still fully unexplained. Were they a result of a ghost sent through the Ouija board?
You'll have to ready the story in full to decide for yourself.

Ever heard of a ghost light? Belief in ghosts in European folklore is characterized by the recurring fear of "returning" or revenant deceased who may harm the living. This includes the Scandinavian gjenganger , the Romanian strigoi , the Serbian vampir , the Greek vrykolakas , etc. In Scandinavian and Finnish tradition, ghosts appear in corporeal form, and their supernatural nature is given away by behavior rather than appearance.
In fact, in many stories they are first mistaken for the living. They may be mute, appear and disappear suddenly, or leave no footprints or other traces. English folklore is particularly notable for its numerous haunted locations. Belief in the soul and an afterlife remained near universal until the emergence of atheism in the 18th century.
Interpretations of how bhoot s come into existence vary by region and community, but they are usually considered to be perturbed and restless due to some factor that prevents them from moving on to transmigration , non-being, nirvana , or heaven or hell, depending on tradition. This could be a violent death, unsettled matters in their lives, or simply the failure of their survivors to perform proper funerals.
In Central and Northern India, ojha or spirit guides play a central role. It is also believed that if someone calls one from behind, never turn back and see because the spirit may catch the human to make it a spirit.

Ghosts in Thailand are part of local folklore and have now become part of the popular culture of the country.
Phraya Anuman Rajadhon was the first Thai scholar who seriously studied Thai folk beliefs and took notes on the nocturnal village spirits of Thailand. He established that, since such spirits were not represented in paintings or drawings, they were purely based on descriptions of popular orally transmitted traditional stories.
There is widespread belief in ghosts in Tibetan culture. Ghosts are explicitly recognized in the Tibetan Buddhist religion as they were in Indian Buddhism ,  occupying a distinct but overlapping world to the human one, and feature in many traditional legends. When a human dies, after a period of uncertainty they may enter the ghost world. Ghosts may be killed with a ritual dagger or caught in a spirit trap and burnt, thus releasing them to be reborn.
Ghosts may also be exorcised, and an annual festival is held throughout Tibet for this purpose. Some say that Dorje Shugden , the ghost of a powerful 17th-century monk, is a deity, but the Dalai Lama asserts that he is an evil spirit, which has caused a split in the Tibetan exile community. There are many Malay ghost myths , remnants of old animist beliefs that have been shaped by later Hindu, Buddhist, and Muslim influences in the modern states of Indonesia , Malaysia , and Brunei. Some ghost concepts such as the female vampires Pontianak and Penanggalan are shared throughout the region.
Ghosts are a popular theme in modern Malaysian and Indonesian films.

After death, a person's ghost normally traveled to the sky world or the underworld, but some could stay on earth. In many Polynesian legends, ghosts were often actively involved in the affairs of the living. Ghosts might also cause sickness or even invade the body of ordinary people, to be driven out through strong medicines. There are many references to ghosts in Chinese culture.
Even Confucius said, "Respect ghosts and gods, but keep away from them.
The ghosts take many forms, depending on how the person died, and are often harmful. Many Chinese ghost beliefs have been accepted by neighboring cultures, notably Japan and southeast Asia. Ghost beliefs are closely associated with traditional Chinese religion based on ancestor worship, many of which were incorporated in Taoism. Later beliefs were influenced by Buddhism , and in turn influenced and created uniquely Chinese Buddhist beliefs. Many Chinese today believe it possible to contact the spirits of their ancestors through a medium, and that ancestors can help descendants if properly respected and rewarded.
The annual ghost festival is celebrated by Chinese around the world. On this day, ghosts and spirits , including those of the deceased ancestors, come out from the lower realm. Ghosts are described in classical Chinese texts as well as modern literature and films. A recent article in the China Post stated that nearly eighty-seven percent of Chinese office workers believe in ghosts, and some fifty-two percent of workers will wear hand art, necklaces, crosses, or even place a crystal ball on their desks to keep ghosts at bay, according to the poll.
Like their Chinese and Western counterparts, they are thought to be spirits kept from a peaceful afterlife.

In Hamlet , it is the ghost who demands that Prince Hamlet investigate his "murder most foul" and seek revenge upon his usurping uncle, King Claudius. In English Renaissance theater , ghosts were often depicted in the garb of the living and even in armor, as with the ghost of Hamlet's father. Armor, being out-of-date by the time of the Renaissance, gave the stage ghost a sense of antiquity.
Ann Jones and Peter Stallybrass, in Renaissance Clothing and the Materials of Memory , point out, "In fact, it is as laughter increasingly threatens the Ghost that he starts to be staged not in armor but in some form of 'spirit drapery'.
