Yes I have heard of this phenomenon several times from qxci practitioners as they discuss it amongst other owners. I believe a box over the shoulder is displayed on the monitor display commonly. Honestly this is a very strange concept. But there are many other enigmas attribted to this machine as well. I would have a blast using this device and the newer scio if I could splurge on a few sessions. I probably would never put it out of mind to be a used one in the distant future. Join yahoo groups qxci english forum for futher insight. BUT please keep us posted here!
By the way, I believe practitioners are serious when they talk about these spirits. I have not formed an opinion personally.
