Scabbars question from Book 1.

I have question to everyone that I noticed once I began to re-read book 
one.
This actually caught my attention and I was wondering if anyone has 
brought it to the groups' attention, so I thought I would ask since I 
couldn't find it in the message logs. At the end of Chapter Twelve: 
The Mirror of Erised (SS/PS, Pg. 214, US Paperback) it reads:

*It was only when he was back in bed that it struck Harry that 
Dumbledore might not have been quite truthful.  But then, he 
thought, as he shoved Scabbers off his pillow, it had been quite a 
personal question.*

Now my question is, why was Scabbers (Pettigrew), on Harry's pillow?  
Is Ron *that* restless of a sleeper or could this be a hidden clue 
that Pettigrew may have already been serving Voldemort as a spy 
again?  Or could I just be over analising this particular instance?  
Could it be possible that maybe he somehow knew, even then, that 
Voldemort was on his way back, so to speak, and was already starting 
to formulate plans and inteligence gathering.  We have no clue what 
information Pettigew told Voledmort once he escaped and found 
babymort after PoA.

Could I have actually found something?  Or am I just overanlising?
I really appreciate feed back, and hope no one tears this up too bad 
since this is my first post.

I also have some more things I wish to discuss about the Location of 
Hogwarts, but I'm not posting till I know no one has brought it up 
before.  I may even try a Tbay for this one. But I don't know.

Respectfully,
Promethia
