Dream: Friend attacks

Last night I had a dream I was at some kind of visitor center for a national park. Some friends of ours were there, and one of them got very mad at this woman and shoved her hard. Another friend of ours intervened and the two of them were grappling near a railing. My angry friend is a big guy and as they were struggling he threw his weight into the other guy and tried to throw him over the railing down to the first floor below. The second friend began falling over the edge and grabbed onto the aggressor friend for dear life and both of them tumbled over the edge. I was watching this take place and I ran out to try to grab them before they fell, but I was too slow. I don’t know what happened, but our friend came back up to the second floor alone and was still angry and sat down. There were tons of people around, including several mutual friends and it just seemed weird to me that everyone was trying not to make a big deal out of it. Everyone seemed to think that someone else would be the one to call the police, but no one did. And no one checked on our other friend who fell over the edge. Was he OK? Was he dead? I never found out.
