I would be "The monster under somebodys bed" And then when the parent came I would turn invisible and then scare here RIGHT in her face! turns into cacooey.
I'd go to a spooky old house that wasn't haunted and share the s*** out of some tourists until a film crew comes in when they hear about the new haunted castle or whatever and I would reveal that ghosts exist.
That is if ghosts do exist. I'm torn on the issue but my mum believes that they are real. Once she was at an old building for tourists to visit and an old women beckoned her to come in through this door. My mum ran to tell her mother and they returned to the door but the door was bolted shut and looked like it hadn't been opened for decades....
I would go stalk some random person, help them and also annoy the s**t out of them. It also depends on wot if people see you or can they hear me or wot can I even do as a ghost. xD
First of all, i need to be a cool ghost. Like a Lich. That would be awesome. Then I'd assault people just for fun or revenge like someone already said.Then i'd spy nice girls while they're in the shower.ME GHOSTA.
I'd get a bunch of my other ghost friends, have a party, listen to "I'm Sexy And I Know It", and sing this:
"Gohstly figures in the house tonight! Gunna scare some fricking people tonight! We'll make you-make you loooose your mind! And all your gonna do is sh-sh-sh-sh-sh-sh shake that!!!"
