The way I do readings...not sure if that is your technique but if someone gives permission I go into their heads and basically poke around for the information and go down the past present or future lines until I find what I'm looking for. Granted I could be a hacker if I wanted(don't even start calling me Black Magicians you strange people reading...lol kiddin) but I'd rather not because I don't want someone doing that to me if they managed to. I like using Tarot because people see it physically though me going around in there head freaks and fascinates people. I sorta slowed down on those readings because I had a teenage tradegy in my life and I didn't want to harm others because I wanted to maim a certain person that should have impotence for the rest of his unnatural life Very Happy anyway...I'm better now but still wary of it.

Hi Imalorki. You mention some interesting concepts in your post. Stepping into someone's energy is a start many readers use, and I don't consider that hacking. Allison Dubois, after whom the show Medium is loosely based, calls "going into someone's head," as you put it, head-tapping.
You also mention going "down the past present future [time] lines." Interesting. A shaman's "journeying" for a client may include doing exactly that, among other things, depending on the need or request, etc. Did you learn to do this spontaneously on your own?
I think you should give it a try for me, the almighty unreadable one. 
From what everyone has said, Kitty's readings have been stunningly accurate, it is clearly an area that she is more developed in than myself, but don't count me out just yet.
