What is the creepiest experience you have ever been a part of/been told about? (NSFW)

I live in Australia, and in my city there is an urban legend everyone here knows about, called the Poinciana Woman. The legend has it that an asian woman was raped by Japanese fishermen, she afterwards discovered she was pregnant and hung herself from a Poinciana tree (see picture here). She is said to be seen in the tunnels of the army bunker at the base, and apparently only goes after men. She is described to be wearing a white dress, with long black hair and pale skin.

A while back, my elder sister, brother and both of their partners decided to drive to the army bases to hang out and smoke weed. They broke the padlock to the gate and drove in, and climbed up the concrete pillars of the bunker to get in, since it's kept locked at night. Here is a photo of said bunker, inside there are many tunnels and at night it is pitch black. They started talking about the Poinciana Woman, and my brother began calling out taunts and they all laughed. Shortly after, they heard footsteps echoing in the tunnel when they weren't moving. My brother claims he ran because he thought it was a security guard coming to bust them, but I know that's not true. They left.

When they returned home, it was around midnight and they went to bed. I was in the lounge room on the family computer, my mum was drunk and blasting music from the television, and my little brother was getting ready for bed. I thought I had heard a sweeping off feet in the hallway, like when you walk and brush the surface of the floor, and the door slightly moving every now and then.

My brother suddenly comes running out into the lounge room shouting, "did you hear that? Can you hear that?!" I was confused, but he went over and muted the television and we stood by the window listening. There was a faint moan outside the window, it sounded feminine and it was circling around the house from window, to window. The wind also picked up with this sound, it went from being a still night to weather during a storm. This went on for ten minutes, the voice got so loud that my brother and I were on the floor crying with our hands covering our ears, but it felt like it didn't help at all and it was as if the sound was inside my head (brother has agreed with this). Out of nowhere it stopped abruptly. The wind dropped with the sound and became still again. I still can't, and don't know what happened and how to describe it. My mum didn't hear a thing at the time and doesn't remember it, my brother and I remember everything.

The only reason I am thinking it was the Poinciana Woman is because after moving out of that house, I finally realized something. We had a poinciana tree outside that window.
