So, the dream is about my bestfriend, I mean, the person in the dream wasn't clearly MY best friend's image. I just knew that it was dream me's best friend. Anyways, at some point in the dream, somehow I knew that the girl was being locked in a small cupboard (and exactly which one, despite not being in able to look into the apartment). The 1st time, we went with lots of police, couldn't find anything, not even the girl. The guy said somethign and the police easily believed him about whatever reason he gave for her not being there.
2nd time, I was with one police lady and she got into the place (it was dark and the only things that you could see was a messy bed, lots of cupboard, kid drawings*). I remember going "check the cupboard. The cupboard" pointing to the exact one. But when she opened it, the only thing there were more drawings. As she was about to leave, the guy (he was suddenly there, or had always been there we just didn't realise) started trying to get to the back of the cupboard.
So I pulled it and there was a tunnel thing, but the tunnel was going INTO the cupboard. Anyways he was like "it's our secret tunnel" and I don't know what was in there, or where it leads to because even dream me was too scared to look. We pinned him down. Then I saw the Ipad.
The lockscreen was a close up picture of the girl, asleep, dead, or unconscious. She was blood on her face and lots of cuts and whatnot. That's when the police lady believed us and finally handcuffed him.
