i don't have the interpretation to this dream... feel free to take a stab
i was hanging out with a couple of friends. there was this giant staircase in the middle of this field so me and two other guys climbed it, the staircase probably went a good 2-300 feet into the air. once we got to the top it was someone's idea that we could get the world record for highest/longest grind so we pull out our skateboards. one of the guys hops on but he doesn't jump high enough to land on the rail instead i see him land perpendicular on the steps go down two of them like that and then go off the stairs and fall the entire way down and splat. me and the other guy stand there frozen and watch as paramedics come in helicopters and ambulances. they put the guy on the stretcher and carry him all the way back up. as the paramedics pass by us we look down at the stretcher and the guy's head is just mashed in but he is still conscious and has his eyes open. as we turn to watch them i realize that these stairs led to this water slide the paramedics place the stretcher with the guy on it onto the slide. the paramedics disappeared and me and the other guy decided the best thing to do was to follow down the slide. we both do and i just remember going down and down for a very long time and sliding through blood.
