Use a prop associated with psychic readings, like a crystal ball or a tarot card. Choose something that will create a more believable atmosphere for your subject and distract them while you're thinking of things to say. For example, you could look into a crystal ball and say something like “Just a moment, I think I’m getting something," when you need a minute to come up with your next line. Choose someone in the crowd and observe them for a while. Listen for any useful information they might share about their life that you can use later on. When you're ready to begin, tell that person that you sense a powerful energy coming from them and you'd like to read them first. For example, if you hear someone mention their best friend Mike, you could bring up the name Mike during the reading to prove you're a true messenger of the spirit world. Don’t make crazy claims about your powers that will set you up for failure. The lower you set the bar for yourself, the easier it will be to meet or surpass your subject’s expectations. You want your subject to be surprised, not disappointed. For example, instead of bragging about how you can read someone’s mind, say something more modest, like “I'm able to sense things that are troubling people, and their problems come to me in bits and pieces. I could try reading you if you’d want that.” Let them know it's up to them to piece together and make sense of the information you’re conveying. You're simply the messenger. This takes the responsibility of connecting the dots off of you and places it on them. For example, before the reading you could say something like “The spirit world relays information to me in mysterious ways, so it’s up to you to make meaning of the things I’m about to tell you.”

TL;DR in Indonesian:
Gunakan prop untuk mengatur suasana dan mengulur waktu selama penerawangan. Pilih subjek terlebih dahulu jika Anda tampil di depan penonton. Usahakan tidak menyombongkan kemampuan ini. Katakan bahwa kesuksesan penerawangan ini bergantung pada si subjek.
