My dad did. He's never fully went into every detail, but he has talked about it in bits in pieces over the years and he said quite a bit as I was struggling with the passing of my mother. From what I know he had a major heart attack and there was a point where the chest pain just... stopped and one second he was there and the next second he just wasn't. He described it as like, leaving his body in some way and being surrounded by light, warmth and peace. He apparently met and was hugged by family members and relatives he hadn't seen in years. He's always been pretty limited beyond that, but from what I gather it felt like they were there to greet him briefly but didn't have the expectation for him to stay with them. Kind of like "hey, we're here but it's not time yet" in the way he's talked about it.

There's been claims in the family he has always been hesitant to talk about but apparently he saw relatives there that died long before he was even born and was able to recognize these dead relatives in extremely old family photos. I don't know how true that is, but whenever anyone in the family tries to discuss it he actively avoids the conversation.
