Only one and I don't know what it was.

It was on a beach in the south of Brazil in the 90's.

It's late night, me and a couple of cousins are going back home. The streets are pretty dark and quiet, we are the only ones there other than the single car passing by every few minutes.

We reach a point closer to home where there is an empty lot between two houses. It's just grass with fences on 4 sides and more empty lots behind it.

The fence is one of those with uneven wood and barbed wire like picrel.

So when we are passing this lot in the furthest fence on top of one of the wooden stumps I see a sillouete. It was too dark to make up what it was. I thought it was a large owl, it kinda looked like one except instead of feathers it had hair. It was either that or a woman's disembodied head.

I point it to my cousins and we stay about 10 or 20 seconds trying to make up what it was, while the wind blew that hair. At certain point we realize whatever we are seeing is not normal so we just bolted. Didn't stop until we reached home.

Now everytime I pass by that empty lot I can't help but stare at it, and where that thing was.
