All that I can remember of this dream is that at some point I was outside during the day, there was a man with light-color skin who was possibly an automobile mechanic who was helping fix someone’s automobile, and after talking with them briefly I walked inside a library.
I went inside a large windowless room in the library where everyone was, somehow I ended up challenging everyone to a fight / sparring match (maybe someone challenged me, and I felt confident enough to extend the challenge so that everyone in the building could fight me at the same time), and so a brawl / sparring match started with me against everyone.
Somehow I was super over-confident and I barely even tried during the fight, I mostly let people try to attack me, and I was so good and / or they were so bad at fighting that they still did not stand a chance against me.
I easily defeated their best people quickly so everyone gave up, their best and / or loudest fighter was a man whose fingertip completely broke off somehow, the man said that his finger could be reattached, and so we picked his finger up and I used some kind of futuristic mini-torch-like medical device to basically weld his finger back on.
I think that maybe the man had the medical device, he briefly explained how it worked, and then he had me use it to weld his finger back on.
The device seemed to have some kind of special substance that helped to reattach limbs / skin / et cetera, it was like some kind of skin / glue-like stuff maybe, but I can not remember.
After welding his finger back on and talking to them briefly about our brawl I left to a slightly fictional version of The E House where I seemed to live with my family, and a fictional door that led to the family room was unlocked to my surprise and I learned that the door handle / lock seemed to be broken so I told my parents who were in the family room.
Then I started to talk to my parents about the library brawl et cetera, but that is all that I can remember of this dream.
