Allochiria is when you feel or see something on one side of your body, but your brain thinks it's happening on the opposite side. Imagine you're playing a game of "Simon Says" and the person says "touch your left ear." You touch your left ear, but your brain thinks you're touching your right ear. It's like your brain is playing a game of telephone with your senses and gets confused on which side is which. This can happen after an injury or stroke that damages the part of the brain that deals with sensory information. It's like a traffic jam in your brain, and sometimes the information gets mixed up. But don't worry, doctors and therapists can help people learn to understand and adjust to this confusion.
