[@Darkod974]There's a difference between controlling one's perspective of reality, and literally controlling reality. One's mentally tricking a person's brain into thinking there's trees growing to crush them, or maggots in their eyes. The other is actually making things fake real and using them to either physically changing them so that they are able to control the environment, and everything else. Water becomes harmless bubbles, acid becomes cake mix, and everything in between. By wording one can make a statement that your one spell does one or the either.
