Weapon to hypnotize

You were a pretty adventurous and kind of stupid kid, so you went to abandoned places to hang out. On one of those days, you went to a big abandoned laboratory in the middle of the forest. Why? Because you wanted to. It was said that a mad scientist worked there and you wanted to see if there was anything of value that you could take with you. Everything inside was weird and dark, everything was dirty and broken. You saw machines and objects that you never thought would exist, but none of them worked anymore. You walked for a long time, checking everywhere, until you found something hidden behind a very worn wall. It was a strange gun full of lights, and it seemed to work. You shot at a wall, but it only released a blue light that did nothing. You looked closely at the gun and it had a label that said "Hypnosis Gun", you didn't believe it, but you took it. Now you're at home, with this strange gun. You want to try it on someone, but you don't know who. You live with your parents and your older sister, will you use it on them?
