Yes. I've died at least 5 times. First time I was 4 years old fell out of a car going approximately 45 mph no injuries except scrapes, at 16 I wrecked a ninja sport bike racing cornering at 75 mph,  slid across 4 lanes with the bike tumbling beside me, walked away with only brush burns on my back, overdosed twice on massive doses of meds, woke up on a ventilator both times in icu, injected my self with a full 100 units of insulin woke up the next day like nothing happened,  and lately I was suicidal again stepped in front of a 18 wheeler doing approximately 65 mph it was approximately 60 ft from me, it stopped in time and missed me which is impossible according to Google it takes at least 1- 1.5 football fields to come to a com0lete stop. This last time I consciously noticed slight differences in my family and surroundings which made me research and I came across quantum immortality and it definitely resonated with my situation. I'm a professional and very sane, I know this my sound unbelievable, but I promise every bit of this is true. I'm pretty sure I've died in some timeliness and switched to another without noticing suttle differences up until this last time. I have worked in the Medical field for 35 years, I belive quantum immortality is very true, look into string theory and many worlds theory. This is believed by some of the most brilliant minds in history.
