For a start, floating might be really fun, but what else might you get up to?
Interesting. I absolutely would horrify people. Especially children. Like ruining their sleep. Mess with them until they are admitted to the funny farm. Grow a habit out of that and do that over and over again, in different areas of the world until I become a legend of a nightmare that actually comes true.
Haunt some of the powerful but evil people in the world and see what I can change. Let’s see how effective a dictator like Kim Jong Il can be with a ghost all up in their business.
If I have poltergeist abilities then I suppose just straight up assassinating people would be possible. After all, if you can shove a book off the shelf or flip a light switch then breaking a few tiny blood vessels in someone’s brain to give them a stroke is going to be easy. Not that killing other people would be easy, but maybe as a ghost I’d have a different perspective on death.
Since I presumably can’t play video games anymore without hands, I’d probably watch others play games over their shoulder and judge them for not playing the same way I would. If they made a really bad misplay I’d probably turn into a poltergeist and start throwing stuff
Test to see if i can take over a person’s body like the movie Heart and soul, then problem just help them do or say the things they want to.
Like a guardian angel, but useful.
Finally get through my r adding backlog. With nothing to distract me and no need to eat or sleep, I might actually finish it in a few decades.
