I don't know the exact answer to your question, but I think Muslims should believe In what was mentioned in the Quran, that there were supernaturals prophets sometimes used to convince their people and sometimes they were gifts they got from god like the ability of Sulaiman to talk to Jinn and Animals.
And [one day] there were assembled before Solomon his hosts of invisible beings, and of men, and of birds; and then they were led forth in orderly ranks. Quran 27:17
We should believe that Moses have done something super-natural (let's call it real magic) and that's why the magicians of the pharaoh believed in him because they as the most knowledgeable people about magic have seen something different and more powerful (doesn't matter if they were practicing something supernatural themselves or not)
Thus truth was confirmed, and all that they did was made of no effect. So they were defeated there and returned disgraced. And the sorcerers fell down prostrate. Quran 7:119
I personally have met hundreds of people who believe that their ancestors could talk to Jinn and do supernaturals, I don't believe it's true yet I think somehow our ancestors were more connected with the unknown world (the unseen, the heavens ..) because they had more stable, spiritual and clean life and I can see that in my mom's dreams and how they mostly come true, this is something supernatural for me that I cannot deny because I have seen it since I was a child.
And talking about dreams, there is a well-known respected western scholar (Carl Jung) who has a spiritual point of view about them:
Carl Jung Talk - The World Within. The Power Of Imagination.
