I've had tons of MLP dreams, usually a somewhat generic story of being in Equestria, and sometimes Ponies leaking into Earth.
It usually ends up in a chaotic being coming to destroy the entire world and me and the mane 6 having to stop it's reign of chaos, or just a normal world and people freaking out due to cartoon ponies surrounding them. ANd with that I become friends with everypony, and stuff.
It's a good dream either way.
