This place seems like a good place to share one of the most weird things that has ever happened to me in D&D
For starters, I don't have any running campaigns, as I don't know very many people who live nearby to run one for me. However, when I visit family members, I'll occasionally join into their campaign for a session.
In this particular session, we (The newcomers) were playing a game of Capture the Flag against the members of the main party. The flags were all on top of towers, and I was carrying another teams flag to my own tower.
During this time, my cousin, an opponent to me, got on top of the party's talking horse (Long story), and teleported both him and the horse on top of the tower, grabbed my team's flag, and then leapt from the tower and landed on my character, stealing a second flag, before running into the distance.
I didn't even try to resist, it was just so beautiful. Hard to explain it in a way that makes sense though.
