Yes they could be real with the existence of parallel universes which quantum physicists believe to be a reality. Certainly an infinite God would want to let many scenarios play out. Far more than in this one Universe. Certainly it would be a waste for us to not see what we could accomplish under a variety of life scenarios. Definitely life could only be fair if we all lives out equal lives of good, and bad in near infinite parallel realities. These scenarios would encompass the would of science fiction, and horror. The only limit would be what God would allow. Some things might be spared because they would be too beyond horrific in nature and might serve no real purpose. Still odds are pretty good that your favorite TV show or movie is a reality in some Universe complete with the same actuals actually being the real people they play as imaginary here in this reality.
