Atheists, how would you explain these Christian testimonies?

[Aoi Magi]

An example of a famous testimony is a former Muslim by the name of Afshin Javid. He claims he was a former Muslim extremist who was in a jail cell in Malaysia. While he was meditating, Jesus appeared to him and quoted bible versus. 

This is all over youtube. There are many videos where Muslims have some sort of "supernatural" intervention where they meet Jesus, and then they convert to Christianity. I am sceptical about these claims but I want to know your perspective on how these could be explained? In the videos many of the people cry and look very sincere so I have a hard time thinking they are just making everything up on purpose. I feel that they believe these interventions took place, whether they did in actual fact or not. How would someone with no knowledge of Jesus see Jesus if it was not real?

Why the heck do you think a muslim has no knowledge of Jesus or Bible when their religion is pretty much a continuation of the bible itself? And even disregarding that, how do you think they know the apparition was of Jesus and the quotes were from bible, without a prior encounter with the book?

There is a reason science demands falsifiability and peer-review of a claim instead of trusting personal testimonies...
