telepathically
If you can read your brother's mind, you can describe yourself as telepathic, or able to communicate psychically.
If someone is telepathic, she is able to read other people's thoughts or to send messages without using any words or gestures. Telepathic ability hasn't been scientifically proven — most scientists think it's fake, or attribute it to intuition or luck — but there are many people who believe they are telepathic. The adjective telepathic comes from the noun telepathy, which is rooted in the Greek tele, or "far off," and patheia, "suffering or feeling."
