This is similar to the idea of "reality as a simulation" wherein an individual is given the following or similar hypothetical: "What if, after you died, a man removed a helmet from your head and asked 'So how was the simulation, how many units can we put you down for?'"

I imagine all philosophical ideas or questions that scrutinize the integrity of reality in this fashion are inherently similar, but what if...

You are a married, middle-aged man with a nice house, two cars, a wife, and two children. One night after going to sleep as you normally do, you wake up in a hospital bed the following morning surrounded by concerned friends and family (or perhaps just medical staff). You are informed that (one of the following scenarios) last time you swore you thought you feel asleep behind the wheel and don't recall how you got home OR the last time you remember getting thumped in the head by a person or object later "coming to" was actually a serious accident. This incident occurred several years ago throughout which time you were in a coma experiencing life in real time (or perhaps much shorter, whichever makes it more surreal). After looking around the room in which you are in, you are aghast to notice a few magazines on the table beside your bed which feature the house you remember purchasing and your smiling kids you remember raising on the cover. Next to them are two model cars you remember saving up to purchase. As a final shock you see the woman you thought was your loving wife of 10 years wearing a doctor's gown asking in a rushed yet polite tone "Can I get some water for you, Mr. Johnson?" You struggle to shake an ominous feeling of dread and doom that you feel beginning to well up inside you and overwhelm your entire being as you begin to ask yourself.. "how long?"

How would you react to this? What would you do? What would you say? Would you trust anything or anyone ever again? Would you want to go back?

Is this a classic example of the solipsist's nightmare? My apologies in advance if any are reading. Or if this is more of a 'lounge topic' than a philosophical discussion.
