Lovers' Duel

This is a brief moment from a vivid dream I had recently:

~I am outside my grandmother's house holding a Blunderbuss (an old pirate pistol with bell shaped barrel) and there is a woman (not my wife) who is my lover (In the dream it was not cheating because my wife did not exist(I have told this dream to my wife in full detail and she is not offended, and finds it funny). My lover also has a Blunderbuss and fires it at me repeatedly as she runs back and forth.
At first I run away to seek cover, but then realize that my lover is a terrible aim and cannot hit me. I begin returning fire in her direction and I must have hit her because she now has 3 bleeding wounds.
We cease our fire for a few moments and walk closer towards one another, but still with guns raised. Realizing that it'll only take one more shot to kill her I attempt to persuade her into a cease-fire.

Me: *with my gun still trained on her head* "Are you sure you want to keep doing this?"

My Lover: *Lowering her guard* "I love you" (This was not a reconciliation, but was somehow a noble gesture/sacrifice that meant I HAD to shoot her and that not doing so would somehow shame/dishonor her)

Me: "Damnit!" *I shoot her in her left temple*

My lover crumples to the ground in a pool of blood and I drop to my knees by her side, crying out in anguish and ripping at my hair. I crawl up next to her and lay down to comfort her in her last moments. Two of our friends who are acting as witnesses for our duel come over, lay an orange apron beside us, and roll us onto it. They each grab an end and hoist us up into the air like some sort of 'airplane ride' one might play with a child. After a minute of 'airplane ride' they set us back down on the ground and give us space.
My lover and I lay in silence for some time as her life pours out from her. Finally, with her last strength she chokes out the words, "Tyler... Tyler was a great guy, wasn't he?"
In great respect for our mutual friend Tyler (who had died years ago (in the dream that is. I have no friend named Tyler who has died)) I said, "Yes, he certainly was a great guy." Those were the last words my lover heard me speak.
Suddenly Tyler is standing next to me. I leap up in excitement and greet him. In great puzzlement I ask, "But you're dead! How are you here right now"
Tyler tries to explain as he points to my lover's body, "I heard her saying my name as she passed away. You see, I hadn't yet completed the transition into afterlife, and because she was only halfway dead at the time I was able to follow her voice back here."

Then there was some confusing business about the Chinese mafia showing up and dishing out idle threats against us, saying we had stolen their family heirloom, and I think they were referring to the orange apron. But I woke up and the last bit was too fuzzy to include as anything concrete.
