So I had a really weird dream, it's a little jumbled but try to keep up anyway.
I somehow managed to get myself trapped in a cave leading to the underdark when it caved in behind me, but fortunately the cleric in our party (because apparently I was in a four man adventuring party) had a set of amulets that would make us look like dark elves ala BG2.
So we went into the dark elf city looking for a way out when we get dragged aside by a couple of friendly dark elves who know who we are and say that there's a patrol coming along who will be able to see right through our disguises.
So then we wind up hiding in this weird labyrnth of tunnels, chambers, stairs etc. But it's not enough, the patrol follows us seeking us out and then...
In come the ponies... with dark skin and pointed ears...
That's right, dark elf ponies, maybe my subconscious just made a connection between on matriarchal society and another, in any case the leaders are unicorns who levitate and use powerful magic that seems to revolver around water, I don't know why water, but they had the ability to send bubbles towards people and trap them in them and fire a projectile that will turn a spherical area it impacts into water (this was the scariest part).
Anyway, naturally we all run away, but some don't make it and I'm on my own with obligatory dwarf fighter, and then we turn a corner and run into a couple of earth ponies who have big metal chompers on their jaws and have collars and chains that are being gripped by a pegasus. They're being used as attack dogs (because enslaving earth ponies would be so dark elf), which is naturally very scary for me, so I run away and leave the dwarf to fight them off.
I'm not really sure about the rest, but I seem to recall dodging around more unicorns for a while before getting hit by one of their projectiles and turned into a water statue, then there was something about being brought to a dark elf Celestia, but I think that was more or less when the dream ended.
So in the dream I was pretty terrified of all this, but when I woke up I just lay there in a daze for a couple of minutes before I burst out laughing.
