"Me? I use gentle and firm method," Arya replied. "I'll enter their mind and make them do what I want them to do. But as long as I don't want to hurt them, they can live their lives normally afterwards."

Most of the time, the target of her hypnosis didn't even realize that they have been hypnotized. Because her methods were extremely gentle and will not hurt the other party.
And if it was not necessary, Arya would not use hypnosis on ordinary people.
Most of it was only used to lead them away from the scene where they would be silenced if they witnessed it.
