What would you do if you woke up from a coma and your life wasn't real?

According to research most people that woke up from comas claim to have lived a full life when in a coma, it seems your mind creates a false reality, one specific story was about some dude that got in a coma from getting hit hard in the head at a playground but from what he claimed, he wasn't in a coma, so it seems his mind created a false reality that continued after his playground accident, he continued living his life like normal until he eventually woke up at the hospital, we can all be in comas right now and this isn't real, imagine waking up one day confused and going like "woah where is my wife and kids?" And a doctor replies with, you were immobilized for 20 years, you don't have a wife and kids, some apparently were in a coma for a short amount of time and claimed to have been living a life for years, pretty insane ain't it?

Ps: some also claimed to see and hear and not able to do anything and others claim to not remember anything at all meaning that for some, some people know how it feels to not exist for sometimes.
