It is not a true but a ‘virtually’ true story. It is one of those stories that come under the category of ‘science fiction’. The characters and events are made to exist by the use of computer software using ‘Virtual Reality Technology’. This technology creates images by a computer that appear to surround the person looking at them and seem almost real.
Nothing can be predicted about future. Technology and intelligence may let it really happen, let us say, after a few decades from now.
