My Story: Hiz.... this happened in the 7th month of this year, which is the Hungry Ghost Festival Month....
One night, at about 12+ AM .. I was using the MIRC to chat, when i have an urge to go toilet... When i came out of the toilet, i could hear someone singing from my computer.... then it suddenly stopped (as in the singing.) I sat down and look at my screen. ABSOLUTELY no music could be playing... so late at night, and someone singing from my computer.... and i have left my cover opened.... but could see nothing.
Another incident is at times, my mouse cursor will be moving by itself, without me touching the mouse.....
that's all...
