Descent Into 13

Two nights ago I had a dream that I got on the lyft at my work and the weight from everyone on it dragged it to the bottom floor. Number 13. Upon realizing this I noticed how cold it felt and how walls of the elevator seemed to cave in. I also knew that there was no floor the elevator could open to since we were well below the earths surface. Instead of panicking I calmly pushed the button that would bring us back to the main floor, Number 5. I dont remember much else of what happened in the dream as I dont recall ot continuing at my workplace but am really intrigued my it. I actually forgot about it until yesterdau my ED was talking about how she needed to use the lyft due to an injury and suddenly the events if the dream flashed in my mind. Interestingly enough a few hours later as she went to use the lyft with someone who she had a meeting with, the lygt got stuck between floors. Fortunatly this wasnt an emergency and they was a large enough space for them to step out of. I am still trying the figure out the significance of not only the numbers but the reverse positioning of the floors (13 being the bottom floor amd 5 being closer to the top)
