I stayed in an ex cartel house turned backpackers hostel in Santa Marta, Colombia. The first night I had weird vibes, the place was huge but empty as it was low season. So i wandered through many rooms to reach the bathroom without seeing people. But it was super eery. My hairs were standing up and felt like I was being watched.
Anyhoo the Ozzy did a tour of the place, usual Cartel stuff then at the end of the tour we got into the ghost stories. During the Cartel ownership a young girl died in the pool and nobody noticed as they were all drunk and merry. This girl has been seen on 3 separate accounts in the garage, in the white dress and dripping in water (pretty Grudge like eh, or whatever that film is).
After the cartel ownership it was a hospital where experimental drugs were used, and most often it worsened the patients. So that night me and the Ozzy girl slept with the light on and did toilet trips in tandem. I woke at 4am and couldnt get back to sleep, but a good excuse to play clash of clans until sunrise. I checked out because of the stories too. Was a bit cowardice looking back, but at the time super scary.
The hostel is Drop Bear in Santa Marta. Other than the ghost stories, it's a super nice hostel
