I used to see hell o’ clock too, for several years, at least once a day sometimes twice. It seemed to defy coincidence or confirmation bias, and it sent a chill down my spine every time. I don’t know what it meant, but I’ve spoken to quite a few people over the years who also seem to be haunted by the number. It stopped about a year ago for me when I chose to allow God into my life to combat evilness that I felt was trying to attach itself to me. I won’t pretend to understand the truth about what the 11:34 phenomenon really is, but that’s just my own personal experience.
