Here is the material that Mormonthink cites with reference to the story of Moroni's visitation. I have added underlining.
Perhaps it was just a dream.
Joseph Smith and his early followers all started out explaining Moroni as a dream, not a vision. Then after 1830 they started calling it a visitation. We can see how these things can evolve, especially if people take the earlier stories as true and want to believe it's more. Here's references that indicate it was perhaps just a dream (emphasis added):
Martin Harris, one of the three witnesses to the Book of Mormon
"Consequently long before the idea of a Golden Bible entered their minds, in their excursions for money-digging, which I believe usually occurred in the night, that they might conceal from others the knowledge of the place, where they struck their treasures, Jo used to be usually their guide, putting into a hat a peculiar stone he had through which he looked to decide where they should begin to dig."
"It was after one of these night excursions, that Jo, while he lay upon his bed, had a remarkable dream. An angel of God seemed to approach him, clad in celestial splendor."

Martin Harris Testimony
September 5, 1829, the Rochester Gem reported on the origins of Mormonism and quoted Book of Mormon Special Witness Martin Harris:
"he states that after a third visit from the same spirit in a dream he (Smith) proceeded to the spot."

Report from the Palmyra Freeman in August 1829
"In the autumn of 1827, a person by the name of Joseph Smith, of Manchester, Ontario Co., reported that he had been visited in a dream by a spirit from the Almighty and. After having been thrice visited, as he states, he proceeded to the spot."

Joseph Smith Sr, the father of Joseph Smith
During his 1830 interview with Fayette Lapham, Joseph Smith Sr. referred to the Moroni visit as"a very singular dream" about "a valuable treasure, buried many years since."

Family living with Smith
A cousin of Emma, who stayed with Emma and Joseph Smith during the dictation of the Book of Mormon reported
"the statement that the prophet Joseph Smith made in our hearing, at the commencement of his translating his book, in Harmony (in 1828-1829), as to the manner of his finding the plates, was as follows... He said that by a dream he was informed by a ghost."

What is the problem about Mormonthink citing these pre-1830 references to Moroni appearing in a dream?
Well, in the case of RayA it may be that he has one of those things called an agenda himself. Mormonthink continues:
Ending summary by critics.
If Joseph had lived on his own then this particular criticism would not be an issue. But since he lived with 10 other people, this is an opportunity to examine whether or not the possibly verifiable parts of his divine experiences can be confirmed by other people rather than just taking Joseph's word for it. Simply put, if you were one of six brothers all sleeping in the same room and your youngest brother sleeping in your very own bed, who believed in magic and finding treasure by looking into stones, told you that an angel appeared in your room last night not once, but three times and lit up the entire room as bright as the noonday sun with his countenance as bright as lightning and conversed with him for almost the entire night whilst you and your other five brothers snoozed away for this entire time - would you believe it?
Equally puzzling is that there is no record that Joseph told any of his brothers, or the rest of his family, about his experience upon waking up. You would think that he would immediately wake up his brothers and tell them what happened. Joseph apparently didn't mention it to anyone until later that day and then perhaps only to his father.
This sounds every much like the alien abduction stories where someone swears that they were abducted in the middle of the night by aliens and taken aboard a space ship but their spouse was never woken up by this. The alleged abductee of course says that the all-powerful aliens have the ability to keep people asleep or erase their memories so their spouses can never see the aliens and verify their stories. To the spouses sleeping next to the abductee, there is no doubt that their spouse was sleeping in the bed with them the whole time, but to the abductee they still think their bizarre experiences were real despite the lack of evidence and the complete absurdity of it all.
I think the key to RayA's indignation is in the last paragraph. He may no longer have a testimony of the Mormon church (RayA will correct if I am wrong), but skepticism about visiting aliens is a redline issue for him, I recall.
