Start of the song "Wolfpack" gave me traumas

I was on a trip in a bus and fell asleep on a bus and I woke up, I have no idea what's going on, I see people talking and I hear some water, then bing, then water again, then violins, then some wierd words, I was wtf is going on and then it, came jumpscare, "To their own shore Came the World War" Then I realised I have my headphones in
