That's why Tsen was saying that these "psychics" use many vague terms, and your own mind believes what it wants to and interprets what the 'psychic' said in words you would think to be accurate. If you want to know about someone's emotions directly though, it isn't difficult if your good at reading people. Of course, there have been numerous accounts of which I would constantly be asked "Are you alright?", "Are you ok?", just because I was thinking about something and had a blank look on my face. Turns out I felt great, I guess those people weren't very good at reading emotions, heh.
