Movies like Flashes - The Director's Cut

John Rotit is quite happy, with a loving wife. Moments later, he's a rock star shooting up heroin. And after that...he's something far more sinister. John unwillingly moves between three parallel lives and knowingly exists in each. He has no clue how or why this phenomenon is occurring. John's judgment becomes even more clouded as his mind unravels, and he'll do anything to end his "flashes" and remain in the one life where he's truly happy.
