All of this — the article you posted, and some of the FReeper experiences described here — is just more proof we live in a simulation, and sometimes the simulation glitches.
Quantum mechanics strongly suggests we live in a computer simulation and nothing in the Bible contradicts this. I certainly think we are.
I've slowly been convinced of this. Seems fairly obvious now.
The closest thing I've experienced to some of the stories being related here, is that my wife and I went to San Antonio when my daughters were fairly young. (5 or 6 I think). We were in the middle of the Alamo, and my youngest said we were being watched. Upon questioning her, she was apparently seeing people near the ceiling. I told her not to worry, that they were just happy that we were there to pay them respect for their sacrifices. She accepted that, and we continued the tour.
