Reach out to all those subjected to crimes.
I have an agenda that would be perfect for this power, let's just say certain people couldn't be re-elected ever again... MWAHAHAHAHAAAAAA
I would make people so scared that they start believing in supernatural things.
I'd go around school and see how people react without me and how the day goes on when I'm not there.
I would sneak into area 51 see what's really going on in there haha :)
Follow my little sisters at school to see how they act when they're not around me. Scare a few people for fun. Spy on people.
Sneak around and scare people. Horror movie style
mmm.. I'd probably just observe people since I like doing that but being invisible would make it easier to notice how people act and such.
