Why do i dream that cops are detaining me?. In the first one i willingly gave in to the cops after coming from school after doing a crime and so they put me in a psych ward which i accepted, in the second i was trying to get home after school too but i was not allowed to enter my block there were barricades and so i had to sneak in i was caught anyway and checked out but i was clean so they let me go. The first dream were the police but the second one were the military
