New Testament scholars Bart Ehrman and Justin Bass had a debate about the historicity of Jesus. At the 1:09:02 mark Justin Bass makes a claim:
Justin Bass: People, of their own religions, do have visions, but across the way, that doesn't happen. [...] Christians are not having visions of Mohammed and Krishna and Buddha. [...] Buddhists are not having visions of Krishna.
Moderator: But you are saying Muslims are having visions of Jesus?
Justin Bass: [agreement] And here's the amazing thing: Muslims aren't having visions of Joseph Smith and saying "Oh! Mormonism is true!" That's never happened.
I spent a long time searching Google, and I could only find one counterexample. I found a YouTube video of a Christian man claiming to have seen Muhammad in a dream, leading him to convert to Islam. So, this alone disproves his claim; however, I believe there is probably more.
Do people have visions of religious figures from other than there own religion, which aren't Jesus?
