Dream of hands, heart, space

There is an alley full of shops of goldsmiths and workers. Next to that is a vertical mine, about the width of a pipe. It's full of star and heart shaped sand and dust. I end up at the entrance and enter for n apparent reason. I squeeze in, it's very dark and narrow and it feels like I can't breath anymore. My throat dries up completely. There is sand and rocks all around me, yet still I try to traverse that narrow, suffocating tunnel by crawling. Then the air gets so thin and I can't breathe. But still I manage to get to relatively open space, and I breathe in all the dust. I choke. But then I see a crevice in front of me with a natural magnetic stone because priceless coins are sticking to it. I pick up some of these coins and somehow manage to get out, I don't know how. Once I get out, I'm out of breath but well enough. I can see a hill behind me, and a very small hole. That's where I came out from, I think to myself. I get up and start walking back home, but I meet up with a family member on my way back. They ask me if I'm doing well. I just hold up my hands and tell them that I got them stars. Because the star shaped sand from inside in sticking to my palms. They get very happy and ask me where I always got it from. I just smile and then I faint, ending up back home. Then I wake up distressed
