You're just in denial about you being dead.I got a bit scared when I was 15 because one night I heard this loud, odd noise like a clock ticking, we were on a campsite so it clearly wasn't a clock and I couldn't work out where it was coming from. Then the next day while we were hiking one of the people we met that day ended up having a fall and dying. Then a month or so later I heard the same noise at my house and again couldn't find where it was coming from, and the next day my uncle died. That was a bit horrible. I started dreading the noise but thankfully it stopped after that and again was probably just another weird coincidence.
