I might have mentioned before that I read a fascinating book a while ago called Phone Calls from the Dead (which is, lamentably, out of print). It was written in 1979, well before the modern cell phone. However, one would think such transdimensional calls would persist into the latest technology, just as phantom voices jumped from vinyl to cassette to telephone wire. Still, I haven’t heard of any cases of ghost cell phone calls. Has mobile technology finally snapped the otherworldly tether? Or will more research reveal another avenue of supernatural communication?
