i had this weird, non-lucid dream a few months ago.

i was deep in this cave, like the ones in Elder Scrolls IV: Oblivion, when i started fighting these angry short people. then this tall lady ran up to me wearing a yellow armor dress thing (like what gladiators wear) and i slapped her on the face and she fell down next to this door. i kept moving forward and i found this door with 2 more short people standing by it, and for some reason i knew their names (Alyssa and Margaret). they let me inside and i was in this rainbow stained glass bowl thing about the size of a football field, and my mum and sister were at the top of the edges behind a fence, cheering me on.

Alyssa walked up to me and told me i had to compete against 9 other people in a series of tests, and the loser from each round was thrown in the dungeon underneath the bowl we were in. in the first challenge there were heaps of silver balls in the center of the arena, and we had to put them in these holes around the sides of the arena. one of the men standing next to me got the least balls in after 2 minutes, so Alyssa threw him into the dungeon.

in the second challenge we had to find a way to get these handles that were dangling from the roof. there were 9 of us but only 8 handles. i dont remember how we got them but this lady didnt get one so she was thrown in the dungeon too. then this really loud, really cool rock music started playing and it was hurting ears. i dont remember any of the other challenges but i won it, and my mum and sister came to congradulate me. then my grandma ran past us on fire, but it wasnt hurting her. then for some reason my mum died and me and sister werent sad. we were trying to push her body into the dungeon, and then when she fell in, i started crying. then i suddenly appeared at home, and i was looking online for my grandpa's business site.

what is the meaning of this dream? i'd appreciate it if you could tell me.
