There are a few different definitions of dead - clinically dead, and brain dead.
A lot of people are describing episodes of being technically dead where the correct term would be clinically dead - but that is where the brain is still functioning yet heart and/or lungs may have stopped due to medical and/or physical trauma. This is also where skilled EMTs can attempt to 'bring you back from the dead' so to speak.
The last term, brain dead is where tests are carried out by two senior doctors (neither on a transplant team) to determine if the brain stem is or is not dead. This is rarely a recoverable situation as heart and lung function are either slowing from autonomic response, or being artifically supported. Paitents in a coma have reduced brain function, but if/when that ceases, which is carefully monitored, there is very little medical intervention to restart the brain.
The medical definition of death is Biological Death, and usually occurs 5-6 minutes post clinical death without medical intervention, and/or within 30 seconds to 5 minutes following brain death.
In relation to the people that claim that they were dead due to no heartbeat and/or breathing for 10 minutes, that is, from a medical perspective, impossible to recover from. It is more likely that CPR was started within the 5-6 minutes of their heart / lungs stopped. Otherwise, serious brain damage would have occured which initiates brain death - a medically unrecoverable situation.
There are recorded instances of people being 'dead' for longer than the 5-6 minutes, and I am not disputing that, but other contributing factors and misreading of the data by observers are usually the answer - i.e. a paitent supposedly dead for 2 hours fully recovered but the contributing factor in that case was that the paitent was exposed to below freezing temperatures where their pulse was extremely slow and difficult to read, as was their breathing very shallow and unobserved.
There are also the claimed 'miraclus' theories, the religious theories and ghost stories etc., These ghost stories I find are normally highly embellished by a third or fourth party, i.e. never from first hand observance. Whatever religious group you believe in, I am not here to dispute. All I post here is from empirical medical and scientific evidence.
