This one happened forever ago. Maybe around when I was 8 or 9.
I was in this big warehouse deal, all they seemed to sell was ladders. They had metal shelves that were miles tall with just ladders everywhere. So what I did was climb a ladder and wherever the ladder ended I would climb across the metal shelve and jump down the other side. This was the entire dream. I repeated those same motions for the whole dream. And it was the best dream I've ever had.
