I'm pretty sure I acknowledged that it can be done for fun (typically, however, only on the receiving end--ACs are quite frequently deadly serious about their "powers") and that there is plenty of room for the things we don't understand, etc. I am pretty sure, however, that the "unknown" aspect of this type of thing comes from inside our subconscious and not from any sort of ESP or special power on the part of the medium. :) We could probably do an excellent job of "reading" our own animals if we were so inclined. Having a third person, however, seems to give us a sense of legitimacy and allows us to feel like we're not just letting our thoughts and subconscious fill in the blanks. Which is still what is probably going on.
But sometimes, it is fun to think there may be some things that just haven't been understood by science just yet and may seem all magical, goofy, or silly. And, yeah, it does just make us feel good sometimes to hear things we want to hear. It IS fun
