There are two types to this power.
Type 1: The type one of this power allows the users to freely manipulate the senses of others. They can make people see what they want them to see, hear what they want them to hear, feel what they want them to feel, etc. But they may be limited by their own power as such people with higher levels of power and energy could possibly negate this type of sense manipulation, they may be incapable of manipulating the senses of people who have high mental barriers, they may require a certain action to be initiated (Eg: Others may have to make eye-contact with the user, etc) so that they may manipulate their senses.
Type 2: This type of Sense Manipulation simply allows the users to alter and manipulate the senses of others regardless of any mental barriers, power differences, etc.
