I had a dream that during a time where my cousins were coming over, there were two people who looked like my sister. I instantly knew one was an impostor so me and one of my cousins tried to figure out who the impostor was. I had an idea. I asked both of them a question only my real sister would know the answer to. My real sister answered correctly and I found the impostor. I told my mom there was an impostor in our house, but she didn't believe me and told me to stop playing around or I will hurt my sister. OK SO
