Just woke up from a dream where I attacked a ******* with a knife

Occasionally I will dream about chasing, general nightmares, physically attacking, some impending doom about to happen...

But I just woke up from a dream where a *******, who looked like Matthew Mcchaunohay(I don’t know how to spell his name[The guy who goes “alright alright alright”]) was there and I had a knife. I could tell by the look in his eye that this ******* has unsavory thoughts about me, sexually. We wrestled to the ground in a green grassy field at midnight. I managed to grab the knife from my holster on my thigh and STAB HIM IN THE BACK 20 TIMES!!! At this point I felt immense pride in myself, because usually I would be the victim in the dream. Ultimately, I defeated the assailant and the dream ended.

What does this mean psychologically? That I am becoming a more brave person who can take care of themself?

Thanks for input. Srs.
