Very Advanced Virtual Reality

It seems like a normal VR headset.

But John knew the truth. Instead of playing out a virtual reality world, it would show pictures of anything follosed by the words 'true self', which would then turn the woman into the image onscreen. So if there were images of dogs flashing on the screen, followed by the words 'true self', the woman would eventually become a human dog, all other memories supressed permanently. It was very powerful technology.

John put up a sign outside his work shop. 'Free virtual reality testing to all female celebrities'. Hopefully it would attract customers.
