Dative reflexives with an accusative object
When you first learn German reflexive verbs, you get used to using accusative pronouns like mich and dich. However, German has a very strict rule: a verb cannot usually take two accusative objects. If a reflexive action already involves a direct object in the accusative case, the reflexive pronoun gets bumped to the dative case, becoming mir or dir.
English speakers tend to trip over this because the extra pronoun often does not translate well. In English, we say that we brush our teeth or imagine a story. In German, you brush the teeth to yourself, and you imagine a story to yourself. Learning to include the dative reflexive pronoun with verbs like sich aussuchen and sich vorstellen is a major step toward speaking natural German.
The most common place you will see this pattern is when talking about your body. In German, you typically do not use possessive words like my or your for body parts if it is already obvious whose body it is. Instead, you use a dative reflexive pronoun and a definite article.
Verbs like sich die Zähne putzen, sich die Hände waschen, and sich die Haare kämmen all follow this rule. The body part is the accusative object, so the reflexive pronoun must be dative. The same logic applies when you injure yourself with verbs like sich brechen or sich aufschürfen.
The dative reflexive is also heavily used for mental actions and doing things for your own benefit. When you memorize something with sich merken or sich einprägen, the information is the accusative object, and you are doing the memorizing for yourself.
You will also see this when you afford something with sich leisten, grab something with sich schnappen, or imagine something with sich vorstellen. Base verbs like wünschen and überlegen often become reflexive in this exact same way when you are making a wish for yourself or pondering a decision.
Some expressions are completely fixed and must be memorized as chunks. For example, sich Mühe geben requires the dative pronoun, as does sich Notizen machen. In constructions like sich etwas entgehen lassen, the dative pronoun actually belongs to the verb entgehen inside the infinitive phrase, but the practical result for you as a learner is the same: you need a dative reflexive pronoun.
When using a reflexive verb that takes a direct object, the reflexive pronoun usually shifts to the dative case. Try to memorize these verbs as complete phrases, such as ich wasche mir die Hände or ich stelle mir vor, rather than assembling them word by word.
