The elevator’s button panel was broken; literally, hanging out.. I experienced a jerk as the elevator tripped and then stabilized immediately but not before giving me an idea of free fall. Maybe if I try putting the button panel in its place, and then try pressing the button, it will work. But because the elevator had sunk, the original panel place was out of my reach. I was trapped in too small space that ensured suffocation and a panic attack was to follow in moments. Then I woke up from the sleep. How lucky is that?
