thanks much help o~o but what if the ghost is hiding under my bed

Immediately find somewhere else to go so you can lead it out of your room. After it's out of your room, grab some salt and make a line of it at all openings which lead to your room. You can also if you want, place shotglass sized cups made from aluminium foil with salt in them around the corners of your room and corners of your bed.

But I can't burn the house down xD
