Get another partnert for the excersices. Try with something easy such as numbers or colors. And from there you choose who will be the receiver and the sender. As the sender you will have to concentrate on the message you want to send to your partner, and as a receiver you concentrate on the person to see if you can come up with the message.
Ah, then you can practice with cards. Playing cards, tarot cards, any type of cards, pictures, or make your own, and try to guess the next one from each other... This is close to telepathy. It is a simple exercise.
I do this with my sister all the time. We use playing cards and take turns projecting or relieving the color, shape, and number. Were really good at it except she usually bursts out laughing after about the fifth card, if im lucky.
