It's called "Ouija", there are various version from the West to the East, but it's pretty much the same rule: A board with characters, more than 1 people to play and several accidents.
The Ouija board was invented to perform fortune telling, like Mariya Shidou said. However, the problem is not because it's twisted with nowadays rumors, but because it was used with the help of spirits. People believed that deceased spirits have power to read into destiny, so they summoned them into the board and ask them for what happens in the future. The reason of the scary rumors was the players can't know what kind of spirit will they summon. If they summon a calm one, they'll just get the predict normally, but if they summon a raged, vengeful one.... you get the idea.
There are two kinds of Ouija play in the East: Ouija Jin (仙 - god, celestial) and Ouija Ma (魔 - ghost). Jin is the divine kind of Ouiji, has almost no chance of curse of haunt, but only high skilled Taoist of Shaman can do. Ma is the normal play which everyone can do.
The tools to play this is a board and a planchette. Mostly made from wood. The planchette is especially good if made from the wood of a coffin (from the grave of course, it's no use if you get if from a brand new coffin which never had a corpse rest inside). If can't get it, you can use a coin or a normal wood, the older the better.
The players are divided in 2 groups: Possessers (no idea how to translated into English so I chose the role to name them) and the Observers. The Possessers can be anyone, but best are kids about 12 years old or so. The Observers are the ones to take the characters into sentences and so on.
The possessers get possessed (of course) to move the planchette. There are differences in West and East Ouija, in the West, the game stops when the planchette goes to "Good bye", in the East, the game stops when you turn over the board and shout "Stop!". The problem is sometimes the spirit doesn't leave the board, thus causing horror like the board suddenly appears somewhere, makes noise and so on. There are several ways to exorcise the spirit, Christian cross or Buddhism symbol (卍) usually do the trick.
So, what do we have for Ouija stories? A LOT! Usually, the horror starts during the game, the players start feeling chilly, hearing noises and the possesser goes mad. Sometimes, the spirit takes over the possesser and drain the life force. If the possesser doesn't get exorcised right away, he will eventually lose his body to the spirit. In which case, a reincarnation. Other stories go as the players' relatives' death was predicted. I can't tell you any story about Ouija board I experienced because I forgot all of them, so why don't you just go for a ride yourself?
Ok, today I was looking at... Chen. A Black Cat of Bad Omen, now now, isn't she cute? Well, as far as I know, not at all. :V
Black cats have always been treated as bad luck and carry evil in the East. They're like shadows, appears in the dark and attack anything. A hundred years old black cat grows a long tail, almost as long as its body. It only appears in nights and whenever it goes to, the lights are out. They usually appears in the house where has a corpse, jumps over the coffin and creates a Jiang Shi (read #1 post). Black cats also have great potential to get possessed by evil spirits, which then feeds on human flesh to go to the next level. They bring very bad luck to the person that see them, but not the same as Black Dogs which brings death. The misfortune black cats brings won't kill the person, but makes him live a terrible terrible life, failures, rejections, hatred and vain.
Why is it? Here is one story... Once upon a time, there was a beautiful girl. She lived a happy life and married a wealthy man from another village. When she was pregnant, they found out that the man already had a wife, but she couldn't give birth so he had to marry another for the lineage. The wife hated the girl, and secretly mixed poison in her drink therefore killed the baby before it was born. Thrice. The girl was upset, and angry. On her death bed, she swore she will come back and kill the wife and all her kids if she ever has one. In the next life, the girl became a leopard, and the wife became a deer. The leopard keeps hunting and eating the fawns and eventually kills the mother deer too. In the next life, the wife became a snake, and the girl became a hen. The snake stealthily ate all the eggs, and then killed the hen. The cycle went over and over again until the girl became a black cat and the wife became her owner. They lived happily in poverty, until a shaman visited and told the wife the cat was the reason of her poverty and bad lucks. The wife didn't believe it, but one day, the cat jumps over her husband, and the next day he died in an accident at work. It was pure coincidence, but the wife recalled the shaman's words and decided to kill the cat. When the knife stabbed, the cat remembered its previous lives, the hatred returned as it refused to die. Due to the extreme vain and anger, the cat acquired the power of youkai and later came back, killed the wife. After that, by defying nature, the black cat turned into a complete youkai and hunt the reincarnations of the wife life after life. Eventually, it forgot the real reason and started to enjoy blood, it then kills everything it doesn't like, and joined in the royal battle of youkai in various wars.
As every other tailed youkai, the weakness of them is the tail, cut it and you can exorcise it. However, many wars proved that black cat youkai is one of the stronger youkai. The nature of the cats makes them a good hunter, a flexible fighter and a tactical survivor. It doesn't have a specific weakness, as it doesn't have immortality trait. So it can be killed by sheer force. Black cat youkai have bad relationship with mouse, horse, rooster. Surprisingly they don't have much quarrel with dog youkai, if unnecessary, the two will just ignore each others.
These guys are reckless, and don't like obeying orders. They don't make friends tho it will stay loyal to someone they've known a long time and have good relationship with, apart from that, they don't care. Even if you're their master's best friend, taunt them and they'll bite your head off when their master isn't looking.
I wonder how much of them is Chen?
But do you allow requests? You said your aunt told many ghost stories. Are there stories that remind you of Mima?
Well this topic is to share, so if I know of it I'll tell you
But I have to say I have little knowledge about Western myths.
Mima looks like a normal vengeful ghost to me, but there are a loads of story on them so maybe I can find one "Mima" in there. I suggest you look on the stories of Onryo.
