At some point in this dream, a man with light-color skin was talking highly of one of his male ancestors, but then he learned that male ancestor was just a European who had gone around raping & killing & stealing & invading et cetera people / countries / et cetera around the world back.
Later in the dream, I played a video game that involved a yard and enemies shooting fireballs at me / my video game character.
All that I can remember of this dream is that I was at an E3-like event, or it was E3, it was inside a large building, and I remember sitting down in a main lobby area with tables & chairs where the open ceremony event was starting.
Part of the ceremony involved a skit that was performed by employees of YouTube / Google led by the CEO of YouTube, Susan Wojcicki, and they were all wearing old style upper class European (maybe French) clothing & hairstyles & makeup & they all had stilts or something that made them all look very tall.
All that I can remember of this dream is that my brother GC & I went to an outdoor class, there was an outdoor classroom with desks, and I brought a backpack & a bag of cloth face masks with me.
While there I remember my brother GC acting like a janitor, like he was working at his janitorial job at The BP Library or something, and I remember some of my former classmates being there as well among the other people there.
This dream took place at a fictional version of my parents house that was or partly was a small ancient European (maybe British) hut-like castle near a body of water, some land, a small bridge, and a street bridge.
The main parts of the house looked modern, but there was a tunnel with rooms along it that was definitely the ancient European hut-like castle areas that were dusty with old objects in them.
