Our factory and my accident

Date: 8/26/2019

So I go to our factory which is different than what we actually have. And I visit the top floor. There's a lot going on here. Some production..some new construction. I notice huge iron (gaaders) channels about 30-40 feet above me. I ask my father, who is actively taking part in the activities, about it. He says this is to facilitate construction stuff movement. Then I see large cartons full of materials hanging, from those channels, by chains. Metal cartons about 6*8 and 5 ft deep. People are pushing them here n there with vigour. Then I notice an aisle of old used briefcases on my right. About 50-60. Then I push a carton myself and I sort of end up riding it and it rushes with speed towards the edge of terrace. I m thinking to myself that there must be some protection mechanism which will stop it from going over the edge but am concerned a bit. And as it approached the edge with speed I notice it doesn't stop and it flies off the edge with me still sitting on the top. It goes across the road to another high building and I try to latch to hit but cannot. Then it hits a small wall of a building and then hits the road. The carton breaks into pieces and I am lying on the ground. I notice it's a temple (sikh gurudwara actually ). I try to stand up and waive to the guy on the top floor of factory and he notices me and rushes towards me. I check upon myself to find I am fine with just a large bump on my forearm and am relieved. There's no pain. I see this guy coming towards me but then he vanishes. I think may b he lost his way which in fact was pretty straightforward. At this I m woken by my son in real life and dream ends.
