Thousands of them, why?

What method do you use to attain them.

Well due to a 'life-time' being an unspecified amount of time with the only requisite being that the life ends; all you have to do is die in your dream. There are numerous ways to die in dreams. You can swan dive off of buildings, jump into the jaws of a tyrannosaur, or have your body torn to pieces by a possessed robot. So many options.

As to experiencing pro-longed types in a dream-state, I have had it happen a few times and I wondered if I had died IRL. One was a rather terrifying dream where I repeatedly woke up, got out of bed - and then I'd wake up, again, get out of bed, take a step - and then I'd wake up, again, get out of bed, take two steps - this continued many, many, many times. Each time I'd get a tiny bit further before it reset. Eventually I actually woke up and I did not want to go to sleep again for a couple of days, it really messed me up. I have had vaguely similar things (but not anywhere close to as long) a few other times, with the only 'method' being that it appears to happen more often if I forced myself to go to sleep when I'm not tired (so for instance after lunch, get in bed, do some meditation until you fall asleep). It seems like my mind then wakes up before my body, there are sometimes hallucinations but I can tell that I am awake and I can see through my slightly-open 'asleep' eyes, but otherwise I cannot move my body. It tends to last a minute or so before I force myself to move /wake up through sheer will power, and I come out of it feeling exhausted and drained on the inside. Not a nice experience. You might want to try that though, if you are really interested. It never lasted for years though.

I don't have a method, they just happen.

When I responded I was referring to the thousands of years long dreams, or at least decades - definitely a higher number of thousands counting ones that just involved dying.
