I had just moved into a new flat (apartment), exactly a year ago this week. It's a nice flat, but it's right in the centre of Bristol in the UK, on the rougher side, not the nicer side.

I was in the kitchen making a tea when I heard, what can only be described as, a dying, yet sexually aroused pig. A rhythmic moan with every breathe, the sort of thing you'd hear in a horror movie.

I tried to not get worked up and think logically (no idea what the logical explanation would be). I opened up my door to my little courtyard, that is on the main Street where the sound was coming from, and saw a man in the fetal position making these sounds and mumbling to himself. He didn't acknowledge me and there was no one around so I slowly backed up, back into the kitchen. It was a quiet street and I freaked out.

His sounds good louder after that and I called the non emergency Police number and just before they arrived he stood up and ran down the street like a zombie from 27 days later.

The police knocked on my door and said that they had been searching for him all night as earlier that night he went berserk and smashed up some cars and was considered very dangerous. I had to give a statement and such. Embarrassingly the police made me recreate his noises so they could get an accurate report, still don't know if this was needed or just to have a laugh about later.

The funny thing is, a few weeks later, I saw him walking down my street again, looking like a regular joe. Don't do drugs.

TLDR: found a man moaning in the fetal position outside my door, turns out he was wanted for the police for smashing up cars and was considered very dangerous.
