"I have question about EVP," writes Lukas. "I just saw film about a man who tried to record EVP of his dead girlfriend. Is recording of EVP and talking with 'spirits' dangerous? There are a lot of things in the world that we cannot solve or that we don't have logical answers for. I am programmer and physicist; I am studying for a nuclear physics PhD. Also, I am living in area where a cemetery once was and is now a block of flats, so recording of EVP here could be interesting. On the other hand, I am living here, and that could be little stressful."
Thank you for your question, Lukas. Recording EVP (electronic voice phenomena) is not in itself dangerous. People have been recording them for many years without incident. There are those who might be frightened by what the voices might say in an EVP -- especially if they perceive it as something threatening -- but perhaps those who are easily frightened should not be experimenting with it.
