The idea of the mind as a sort of antenna wouldn't be controversial to me.
It would be controversial unless proof was provided otherwise.
It would be extremely alarming b/c every spammer in existence would immediately resort to "brain spamming" as a way to short-circuit e-mail and our current relatively protective spam filters. We would have to begin wearing anti-spam helmets to save our sanity and our thoughts. Criminals would (effectively) shield themselves from prosecution by claiming that acts of crime were transmitted into their brain.
IIRC Philip K. Dick had something to say about all this.
It is certainly possible, but it would require a rethink of our current understanding of nature. That has happened, but most of the time when presented with anecdotes like this... it does not happen.
