Reflective pronouns (myself, yourself, himself, herself, itself, ourselves, yourselves, themselves) direct the action of the verb back to the subject. They show that the subject is both performing and receiving the action.
Here are some examples:
* She dressed herself in a beautiful gown. (The subject "she" is both performing the action of dressing and receiving the action.)
* The dog licked itself clean. (The subject "dog" is both performing the action of licking and receiving the action.)
* We helped ourselves to some cake. (The subject "we" is both performing the action of helping and receiving the action.)
