I don't get quite that same phenomenon, but I have had all of a object's history (say, my house, for example) jump into my head at one time. Hurts (mentally) like crazy for a minute, but when the "pain" dies down, it's amazing to see up to a couple hundred years of history almost visually happening all at once for a couple minutes. Really, until I stop focusing on the object.
That's what happened to me when I saw the Pantheon in Rome. Hundreds of years of history just >BAM< showed up in front of my eyes. THAT time, it was truly awesome.
