Picard: One of us is hungry. Crusher: That would be me. Picard: Would you mind thinking of something else? You're making me hungry. Crusher: What do you want me to think about? Picard: Something other than a large bowl of vegetable soup. Crusher: My grandmother used to make it with peas, carrots... Picard: Beverly!

Picard and Crusher have been taken captive and had devices put into their brains that let them experience each other's thoughts.....whether they want to or not.
