Paradoxymoron

There's a voice in my head, maybe.

 Possibly even two of them, i think. 

 They speak to me constantly, only sometimes. 

I don't really know what to think, i don't think. 

It lurks in the back, but stands in the forefront. 

It speaks to me slowly, often times quickly. 

 One may think that I'm sick, yet I'm perfectly healthy. 

Time seems to move ever so quickly, yet every clock i see stopped at Eleven. 

I'm stuck in the middle, I'm nowhere. 

Surrounded by friends , all alone. 

This thought process never really existed, as always.

 I sit still with one mind, it has three voices. 

Move along now, there's nothing to see.
