Fear of hell, advice please

[orthodox-man]

guys, I have read some of the Japanese accounts, they are very similar to Christian ones, but usually consist of no deities. I also read a search for Muslim NDEs by Kreps, where he collects a few, but even he says he would have expected many meetings with Muhammad in these NDEs as people report dreams with him or visions of him, so again, I don't get why they cannot hallucinate him. How can you guys be so confident these NDEs are not real?
