Do Ghost Exsist ?

Recently , channel u and channel 8 have been showing some ghost movies . This reminds me of one of my neighbours . He is in primary 3 this year and claim that he have Yin Yang Yan (the ability to see ghost) . His mother thought he was lying at first . When he was younger , he suddenly ran out of the bedroom ( crying ) to find his parents . He told them that an auntie had touch his head in the bedroom when there is no one is his bedroom .

Even more recently , he ask his mother ( who is washing the dishes ) whether she see a lady at the void deck of the opposite block . His mother replied him no and ask why did he ask that . He said that he saw a lady with legs not reaching the ground ( not facing him fortunately ) there . Also around that time , there is a lady from the opposite block jumping down the building .
