what if...you landed yourself in a parallel universe...?

in your own universe you live your everyday life whether you are happy or sad [you know whatever your life is] then one day you were just taking a stroll when suddenly the world around felt different. you stumble upon the graveyard to see your own name engrave on a gravestone and you died [of your own choosing for this scenario] you later decided to visit some local library or perhaps stumbled upon a slightly outdated newspaper saying that you were well loved and missed. would you replace yourself and confirm you're alive by visiting grieving friends and family of that universe?
