Snape's Loyalties

I just began to wonder about this and am without my book here at 
work. I am wandering down the road of thought that Snape is really 
posing as a spy but working at times for Malfoy/Volde.

During Occlumency lessons Snape gleens that Harry has been having 
dreams of the Dept of Mysteries.  He also can gleen that Harry is 
getting futher in his dream-explorations of the route to the prophecy 
recording.  I wonder, do we actually have any proof that Snape is 
keeping the Order/Dumbledore informed about Harry's continual 
dreams?  Or that Snape has been instructed to help PREVENT these 
dreams?  (Besides Hermione's assumption that this is the purpose.)

Snape tells Harry to "clear his mind of all thought" both to begin 
Occlumency and when he goes to sleep at night.  Now, we don't know 
much about Occlumency except for what Snape tells us.  So maybe, 
Occlumency, often practiced to summon up thoughts and memories, is 
actually most difficult to defend against if your mind is open and 
empty--allowing anything to be clearly seen as it is probed--the 
opposite of what we are led to believe as Snape "guides" Harry to do 
to defend against it.  

Why would Sanpe do this and how would he expect to get away with it?  
Well, if his only assignment is to teach Harry Occlumency and not 
necessarily to stop him from dreaming at night, but rather to enable 
Harry to maybe learn more sensitive information about the order, the 
prophecy, etc and not be a leak to Voldie. Then, perhaps, Snape can 
justify his teaching method (clear the mind) as maybe being most like 
the mental state that is weakest to defend against-- in the theory 
that if Harry can defend from that state, then he can defend against 
anything.  So Snape has his alibi for WHAT and HOW he is teaching 
Harry and he also has reason to urge Harry to "practice" this 
clearing at night which is really opening the pathway for Voldie. 

If I were Snape and I wanted to secretly urge Harry to find out more 
about this mysterious door, room, etc, then I would tell Harry that 
is none of his business. We all know how curious HArry is.  

Any thoughts??
