Lily *Did* Scream and Happy Thoughts Conjure a Patronus

A couple of weeks ago, Richelle questioned the accuracy of the scene 
in the movie that JKR personally added which shows Lily screaming 
when Voldemort hits her with the AK.  In flipping through PoA last 
night, I actually found a straightforward answer to this question!  
In Chapter 9, during the Quidditch match against Hufflepuff, when the 
Dementors show up and Harry starts re-living his parents' final 
moments, it reads "A shrill voice was laughing, the woman was 
*screaming*, and Harry knew no more" (p. 179).

On a different subject...my kids were watching Peter Pan this 
morning, and it struck me that in order for Wendy and her brothers to 
fly, they have to think "happy thoughts."  I wonder whether this is 
where JKR got the idea for a wizard needing to think of a happy 
thought in order to conjure a patronus?

Cheers,
