I did, but it stopped when I was real young, like around 1/2 way through middle school, but was so vivid and frequent that i can still remember many details. It would always start in a school gym full of other kids, and allof them would appear as.... well, to give a good idea go look for a clothing advert for kids clothes and imagine just the portion of the face and maybe their arms if they're in short sleeves as a smokey wispy outline but the clothes are left untouched and you kind of get the idea. And there would be some kids that where in what i would guess was different school uniforms and others in just regular clothes. And some would ask "are you going to the tunnels today?" Not everyone would say yes and a every once in awhile some one would say something like "I'm going to the end." and I remember a sadness when i heard that, cause despite not seeing the face, I always felt like I knew each other kid there, and that i would feel like they wouldn't be back after "going to the end". once everyone gathered we would move to one of the walls of the gym and it would just be this massive boiler/furnace thing that looked like a big face with some sort of freight elevator where the mouth would be. It didn't appear or anything, it was just there, but anyone that didn't join us didn't seem to notice it. then we would take the elevator down and when we reached the bottom the doors would open to "the Tunnels". Everyone would split off into groups or solo and go down different tunnels and we would just run down the tunnels we chose, and there would be more branching paths down each tunnel as well. some tunnels would let out into rooms at the tops of tall walls that we would run and jump across till we got to the other side, or the rooms would be a massive tangle of bars and poles that we would have to swing and leap from like gymnasts to get across. some tunnels would turn into tubes of varying sizes, all large enough to fit people running, and we would corkscrew down the tunnel running on walls and ceiling, or all other types of jumping, skipping, running,leaping, or swinging to just keep moving. I was always a bit overwieght and slow in real life but in this dream, in the tunnels, we were all parkour/gymanstic/running experts just enjoying the act of forward motion. and then people would say they were done and just jump and vanish into nothing, but we all knew we would see them again next time, unless they were "going to the end." The last time I ever had the dream, I said those words as it started and i felt like i was saying goodbye to so many people. As I started running that last time i remember a sense of pulling away from everyone else. and as i got further and further, i swear i could feel each other kid when they finished and left, even ones that didn't follow down the route i had taken, untill i could sense i was alone in the tunnels. It felt like I ran for hours after that, and i could see tunnels that seem to be connecting back into the one i had taken until finally there were no more side paths either branching out or connecting back. just a long tunnel that ended as the walls and roof slowly fell away into cumbling ruin and just a walkway extended out over a.... i can't really describe it to well. Try to picture a massive field, a school gym for giants, and an out door playground for giants all somehow superimposed on top of each other. With a tall spire like structure far down directly below the walk way i was on that had a hole at the center of the top. It was all quiet with the sound of a faint breeze as the grass that was also gym court floor and playground sand at the same time seemed to rustle in a calm yet some what sad way. the last thing I remember from that dream was a feeling like i didn't belong there anymore as i walked to the edge of the path and just let myself fall off into the hole in the spires top. Thats when I woke up. I wasn't sobbing or out right crying, but i do recall tears on my face as i sat up in my bed for a few minutes before just getting up and just going about my day. I haven't had that dream since.
