As we move deeper into the digital age, is it possible for the dead to tap into our electronic frequencies? I remember the scene from Poltergeist (1982) where the girl is watching the TV. Then again in the film White Noise (2005). And now this from BBC...

This is like a good mystery movie where you start adding up the facts in your mind.

A man dies. His friends receive emails from his email account months after his death that have short, personal messages that only the deceased would've known about. His mother, a spiritual being, chalks it up to divine intervention. At first I thought the obvious. Someone has his password and is pulling an 'Ashton Kutcher', but after hearing the testimony of the friends insisting no one would have known certain facts and conversations, I have to go back to my example above a la Hollywood...that just maybe digital frequencies allow communication from beyond the grave.

What are your thoughts? Is this a science thing? Is this a spiritual thing? Or is this just one big hoax?
