Sleep walking issues?

i often sleep walk to my car and drive to the store and spend way more money than my budget can handle. the doctors tell me im probably dreaming but i know i am not because one time i woke up at the damn convenience store!!! i would go back but now im nervous because i woke up this morning with blood on my night gown and scratches and bruises all over my body and a shot gun in my bed!! no one in my house was in danger thanks god but i know my neighbor says her husband has been missing all day!! what the hell should i do!!!
