I've had one or two...I had one where I was my ponysana and Discord was back to spread chaos in Equestria. I found him in my real-life neighbor's backyard (which for some reason was in Equestria), picked up a rock, and tried to throw it at him (I wouldn't do the that if it were real), but it missed. He watched it fly past his head and then sarcastically told me "Good shot." before reaching down to grab me. I backed away until I hit the corner of my neighbor's fence and I actually felt scared. My dream suddenly ended. Rather short.
