Kia Ora Shawn,
A couple of months ago a young Maori girl who worked in one of the local shops on the island, committed suicide. Her tangi= Maori funeral] was held at the local Marae= Maori 'spiritual' meeting place. Well at the time of the Tangi, the power went out in the shop where she had worked 'nothing strange about power going off' but the power went off at the same time the Tangi started, the local electrician couldn't find the fault... The Tangi lasted four hours and the power in the shop came on again at the same time the Tangi ended...Local Maori elders from the Marae performed a 'blessing' to remove the 'tapu' :
"The origins of tapu date back to the time of creation and the gods: Ranginui - the sky father, and Papatuanuku - the earth mother, and their offspring Tane Mahuta - god of the forest, Tangaroa - god of the ocean, and their divine siblings.
Tapu is closely linked to the Māori concept of mana (respect / authority) and many view tapu as the mana derived from the gods.
In early Māori society, almost every activity, ceremonial or otherwise, was connected to the maintenance and enhancement of mana and tapu.
To maintain the sanctity of tapu, certain behaviours or actions were prohibited.
To disregard the rules of tapu was an offence to the gods. Those concerned forfeited divine protection and were therefore exposed to supernatural evils.
The most common manifestations of this evil were disaster, demonic possession or death. These consequences could also apply to family members, lands and tribes.An individual's level of tapu increases to maximum levels as death approaches.
When someone has died, a tohunga or a priest is called in to remove the tapu from the place and possessions. If this act is not performed, those in contact with the tapu objects are put in danger.
Burial grounds, ceremonial sites, carved houses, and waka (canoe) carry tapu requiring certain restrictions in behaviour.
Women are not permitted to enter a carved house while it is under construction. This undermines the mana of the house, and also the mana of the tribe building the house. Once building is completed, a ceremony reduces tapu so that it's safe to enter.
Fresh water has a special connection to tapu. It has the power to neutralise tapu to levels that are no longer dangerous to people. After a visit to a burial ground or funeral service, water sprinkled on the body lowers tapu!"
Days after the Tangi local shoppers and staff reported things flying off the shelves, again not unusual if an item is not stacked properly and close to the edge, a little bit of vibration could send it tumbling to the floor. Just before the Tangi the mother of the young girl called into the place where I work, she's known to my work colleagues , well anyway, she had mentioned that her other younger children have been smelling perfume, the type her daughter used to wear throughout the house, and doors have been opening all by themselves, but when the mother was telling us this, it was in a matter of fact kind of way, nothing unusual about this kind of thing happening when somebody dies'...
Well I shop at the shop on a regular bases, once, twice a week,[it's my local], so there I was in the store bending down to pick up some tofu from the cooler shelf, when all of a sudden whoosh then 'thump,' a packet of coffee had flown off the shelf behind me...I immediately looked around, nobody was in the aisle [the shop wasn't busy] then when over, picked it up, walk around to the other aisle thinking somebody must have pushed it off whilst grabbing something off the shelf behind, I should add how the coffees were stacked on the shelf someone/thing would have had to use force/energy to push it forward aprox 6 inches to the edge and then over to the middle of the aisle, but there was nobody in the aisle.
I should point out when it comes to ghosts, fairies, etc, I'm a sceptic[I'm so sceptical that I don't even believe in my 'self'... old Buddhist joke

]...
So as this first hand experience changed my belief in ghosts ? No not really...Energy is just energy and ones life force is energy... I believe, it's possible the thoughts of this poor young girl' who committed suicide[ thoughts are a form of energy, so I believe] were in such a state of bottled up anger and frustration regarding her life's predicament , [she had just split up with her boyfriend and she was [I was told] 'pregnant']. The energy generated by all these 'unhappy/negative thoughts still needed to be released, hence the things flying off the shelves, etc...
Now I could be wrong but for the time being, this energy theory sits well with me...
