All of startrek is just a illusion by the Talosians to keep Pike and his decendants in line on Talos anyway.
Wouldn't that make his simulated life after his accident an illusion within the illusion?
If it keeps him docile and compliant.
To be honnest its a joke but if you think about it.....
Pike seemed pretty unwilling to live a life of fantasy....so give him the illusion of freedom with bad events as well as good. The accident could all have been a illusion to make him submit to there will
All of startrek could just be illusions of his descendants....
