Acts 10 contains a ludicrous story that Christians believe, because it is in the New Testament, although it is clearly nonsense, that no grown up person should take seriously.
He (Peter) became hungry and wanted something to eat, and while the meal was being prepared, he fell into a trance. He saw heaven opened and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals, as well as reptiles of the earth and birds of the air. Then a voice told him, "Get up, Peter. Kill and eat."
"Surely not, Lord!" Peter replied. "I have never eaten anything impure or unclean."
The voice spoke to him a second time, "Do not call anything impure that God has made clean."
This happened three times, and immediately the sheet was taken back to heaven.
NT Wright would say this was not an hallucination, because Peter knew perfectly well what an hallucination was and what an hallucination was not.
I guess there is nothing that Christians won't believe. If somebody claims to have seen food that was not there, they will say that it was not an hallucination, it was a 'vision'Wright on the Resurrection
Here a Christian explains that this bizarre story was not an hallucination, it was a vision.
A sheet containing all kinds of four-footed animals was not an hallucination, because it was a vision?
You have to laugh at these people....
