Less a ghost story and more of how strong the brain can be to make you see and hear things:
So one summers night, desk fan on in the room, i wake up in the middle of the night to a female voice laughing almost cackling, i look to the corner of the bed and i swear i see a little girl with a white dress and long black hair, I noticed that I start to go into a panic, my heart racing. During the years I had luckily taught myself, that whenever such situation arrived, that I should just breath, and so I start breathing, in and out, deep breaths in and out, until slowly my vision gets used to the dark and what only could be described as an hallucination, the girl, disappears. Calming down further, the laughing I had been hearing up to this point was actually again my brain tricking me, as the laughing had changed to the simple noise of the fan running.
With myself eventually calmed down, I sat up on the bed, stood up breathed in and out one more time, and then simply went back to sleep. The girl hallucination I had been seeing is easily from any Japanese horror film/game which I had seen before. The real scary and annoying part, is why the heck would this happen? as if my brain purposefully made me scared.
