I really love this passage from chapter one - I can imagine it perfectly. The way you describe this feeling is perfect.
"My eyes pop open and seconds later, I’m sitting up in a strange bed in a strange room about to panic—or pee my pants—when a thought holds me back. There’s something I’m forgetting. I know there is. I’m here for a reason. A memory niggles at the back of my mind, like the words of a song just on the tip of my tongue. And just like the words I try to remember, the thought alludes me, delving down deeper into the folds of my mind to escape my grasp."
