I play on a server with inventory pets, and evilcraft. In evilcraft you can craft an enderpearl with some blood, a slimeball, 4 glowstone, 2 lapis, and 2 redstone. So I made an enderchest pet.
I had an idea that I could get from the dream world to the real world via the mirror, But when I tried to enter the mirror in the spirit world. I woke up. When I went back, my stuff was deleted.
