Well, he gets to do that. It's called a belief. And he doesn't have to defend it unless he's asserting that it's more than that - i.e. that it's true for anyone but himself. Since I don't see him asserting that the rest of us must believe his experience was supernatural, the rest of us don't really have the right to challenge it unless it pleases him.
I'll assume you're talking about one of the ones I've had. The experience involved answers in the natural world that I didn't have an answer for, but were true.Like if you ask a bus driver "what time is the next bus" if he doesn't answer, you will not know, but if he does, and is correct, you do. Replace the bus driver with some sort of invisible entity that made you feel amazing while it was there. So me not 100% believing in God at the time, or the supernatural it was an amazing experience for me, I felt a beautiful presence which I was blessed to communicate with. I didn't want the encounter to end. The song "I want to know what love is" was answered as well, I know what love is, and it's incredible.
I've received answers from nature, random circumstance, a random song playing on my playlist, a thing someone said on the radio... These are likely natural coincidences that seem more significant than they are. Dawkins wrote a book about it called "Climbing Mount Improbable". Some may be the result of your own subconscious, particularly beautiful images. Some the result of natural chemicals in the brain. How do you tell the difference between that and the thing you call supernatural? If I ask someone to pick a number between 1 and 10, and I get it right, does that mean I read their mind? Or does it mean that I had a 1 in 10 chance of getting it right?
