You know what you can do if you are invisible?
For instance you can come to a child that knows nothing and give him thoughts to focus on something and try and make it move.
And then when you move it while he is concentrating on the object he thinks he can move things with his mind.
Think of all of the possibilities, all of the illusions you could do.
You can also make people think they can see the future, you can give him thoughts of something to happen and then make it happen, he thinks he can see the future then. Although this is possible, you can chart future events due to cause and effect if you have enough of the variables, sometimes it is illusion given to people and not actual charting.
So many illusions can be done if you are invisible.
