It is thought experiment by Robert Nozick used to debunk hedonism. The general premise is what if you had a machine that simulated a life of only good experinces or any experience you want really.( I assume the indivdual is omnipotent in there world, but I don't know). But all the experinces they do are not actually happening. The person is really in the machine and they don't even know it. I guess what Nozick was trying to do was get the thinker to search within themselves and think if they perfer the real world over the fake world then something other then pleasure must be good in itself.( people talk about it on youtube for more info).
