Rofl, pretty strange. ^^
I have no idea what ravens stand for. xD Maybe it is kind of normal that they come as a flock, but I would never cease to seek divinity in events that touch you. If it touched you in some way, maybe it was meant to, who knows? I wouldn’t look up definitions to find the answer, I suggest to look inside. What was the first feeling? What is your first associativity that comes to your mind when you think of ravens? Was there something in your childhood or maybe not so far away at all? Is there something you can connect to any aspect of the event?
Maybe it will all come down to the fact that it was a nice, strange and somewhat other-worldy event, than take it as that. Maybe it was meant to simply show you that otherworldy things can happen to you. So be glad that this was offered to you! 😆
