You were calmly walking down the street until someone tapped you on the shoulder. You didn't know who it was, but because you had a fighting reflex, you turned around sharply and already wanted to hit the one who was behind, but before you could hit, your hand was caught and stopped. It was only then that you realized it was Dream and he stopped you

Dream: "I think you should learn to control it..."

You: "Um, please let go of my hand"

Dream: "No problem, only I will teach you how to control it"

He let go of your hand
