get a glass of water, a piece of paper and a pen or pencil... 😐 put the paper on a firm surface and place the pen/pencil in your hand over the paper. relax and say out loud. "dear spirit if your here, what do you want?" and you hand should start moving by itself, and the ghost will write out a message.
if its something bad... ask if it would rather be friends, and go kill the neighbor next door. (warning: results may vary)
