Trapped in narrow Concrete hallway Dream meaning

"i was trying to find a shortcut back to my car after grabbing some groceries, but I accidentally ended up in this long, narrow concrete hallway beneath an old office building. the ceiling lights were flickering and hummed super loudly, and the air smelled like damp dust and rust. i turned around to go back the way I came, but the door I just walked through was suddenly completely gone--just a solid brick wall in its place. i started walking faster down the corridor, opening every single door I passed, but each one just led into another tiny, windowless concrete room that was completely empty. my heart started hammering against my ribs, and my breathing got really shallow. i tried to use my phone to call someone, but the screen was just displaying gibberish letters and wouldn't register my touch. then the walls started slowly shifting inward, making the hallway narrower and narrower until I had to squeeze sideways just to keep moving forward. i tried to push against the cold concrete with both hands, but I couldn't get any leverage, and then the lights went out completely, leaving me squeezed in the dark with no air left to scream."
