Dream About Being Trapped In A Tunnel

I needed to get to this location and the only way to get there was by using a small golf cart. The only problem was that the cart was placed inside a concrete shaft which required the person riding the cart to lie down as if in a coffin. The shaft had an equal amount of openings though placed in between all the enclosed parts. I am very claustrophobic, however I decided that since the tunnel had so many openings I could sit up and catch a breather in between the closed parts. I got in the cart placed my hands on my chest and started going however when I reached the opening I realized part of it was covered by a thick ridge on the side of the shaft and there was not enough room for me to get up. Looking ahead I saw they were all similar. I knew that probably not all of them were like that and I could get up in a few places but soon the realization hit me that I was trapped there and there was no way i was going to have any chance of getting up any time soon. I started to panic of course i could feel my heart beating out of my chest, my breaths grew more frantic with every second. I remember thinking that in my life i have experienced panic attacks before but i could sit in a fetal position and hug myself tight and drink water but now i couldn’t even sit up. Using all the adrenaline induced force i could muster i stopped the cart with my legs and started pushing myself back towards the entrance. Finally after painstakingly pushing myself back the way i came now getting back out of the tunnel would be the new problem. It was very tight and i was already shaking alot. First i pushed my torso and then my legs were the most difficult to get out. When i got out i remember there was a crowd of onlookers which included some people in my family like my sister. They booed me for not being brave enough to reach the other end. The tunnels were made of dark grey concrete and mimicked a brutalist style. They looked bleak and cold. A reflection of the dark places in my mind. After being booed, i tried to get back in the tunnel a couple of ways I tried walking forward alongside it and trying to fit in some of the gaps but it was no use. Eventually i gave up and accepted that i was not reaching the other side through this tunnel.
