I just had a terrifying nightmare

Today I had a ing scary nightmare.

I dreamt I was in a group of lawyers and we had this new case where they had found dead an 8 year old boy, not knowing who he was because he wasn't of this country but then managed to track down his adoptive father, who was living on a pension for kids. I remember arriving to the scene to find the town being on the place, angry at the man and trying to get some justice on their own. The man had wounds but there were some defending him, not believing he had killed his kid so the police had to get in the middle before things got too out of hand and we took the man away.

The group I was consisted on other two girls and we were all trying to seeif the guy it's telling the true or not, and a first he denies everything but then a thing slipped out "Stupid thing from a stupid country, I wanted their nationality not their kid" which indeed made us think he was guilty so we started building a case against him. We worked on a secure space but he could see us from the other side of the bars, he often had this sadic smile on his face, very sure we would find nothing on him. But then the guy's mom started working with us and she ended up saying things that gave practically the whole case to us. She said that he would get enraged at the boy often and that his daughter cried in fright. We didn't know he uad a daughter so now we had a weak point. So we told him that we had gotten an order so he would never get close to his daughter again, he was cocky saying that we couldn't do that but then we told him shat his mom had said and that we had him now. He became a monster then. He started yelling how the boy deserved it and that he had never wanted him anyway and that we would pay for taking his daughter away.

He would always stand close to the bars when we worked, looking for any kind of opening so he could hurt us so now we had extra security and when the case came through and he was sentenced, he swore he would find us and kill us. It was three of us but I felt the meant it for me. The last part of the dream was me obsessively trying to lock every door around my room but there were too many and he could slip in at any moment, he could escape and come to kill me and I couldn't sleep because I needed to be vigilant. I woke up from the nightmare scared out of my mind, with the feeling that the man was still lurking in the darkness, waiting to kill me.
