I wake Up

In midst of fighting Percy get knocked out. He wakes up in the hospital
His parents tell him he has been in a coma since he was twelve and he realizes his whole demigod life was all a dream....
All a dream

He goes to halfblood hill,gone

He finds his friends, no memory

Annabeth, never has heard his name

But is there still hope to find a dream

A dream that could only be imaginary
