SEP has good article on bodily awareness:

"The notion of bodily awareness is at the crossroads of philosophical debates on the self, perception, action and space. This entry will focus on three main questions: (i) How does the awareness of one's body differ from the awareness of other objects? (ii) What are the roles of action and mental representations of the body for bodily awareness? (iii) What makes us feel our body as our own?"
