help me figure out what it means

i need help figuring out what just happened in my dream, im still learning to control my dreams and im still trying 2 recall enough but here it is.... me and this random old lady i dont even know each had a hidden blade (basically a wrist bracer-type thing with a retracting blade on the front of the wrist) and we were stabbing each other with them, like incredibly violent stabbing and neither of us were dying. thats it, i remember stuff happening before but only to the extent that something happened before that i have no idea what it was though.
