I was so damn scared the whole time we were inside the hospital. I could feel an evil presence the moment we stepped into the building. You could spot satanic marks drawn on the wall in some rooms, which made it even more horrifying. We also got scared by bats a few times and once we even heard a heavy thud from the floor above us. This ran a chill down my spine. Later on, I heard a voice sounding like Lucinda, saying "guys" down the hallway. But Lucinda was standing right next to me and there was no way in hell that she could have said that. That definitely made me want to leave the building right away!
We explored almost the whole hospital. One place we didn't go was the morgue. Since we know the history of that place and what happened there we decided not to take a chance. So we let that part of the hospital be, maybe for the best.
Once done exploring, we left the haunted premises of Old Changi Hospital. We got out safe and sound and without tripping any alarms! Phew! Still, after we left the hospital we all had a weird feeling of anxiety bothering us and I had a heavy feeling in my chest. That night I had some vicious nightmares.
There are plenty of explorer's stories online. There is one special occurrence that has happened to many groups going to the hospital to explore. The story goes as: usually one of the group members start following a person that they believe is in their group. They then follow that person further and further away from the others in the group. The scary part is that the person they were following never belonged to their group, meaning that it could have been a ghost or a soul. This entity will then either lead you out of the place, or to a secluded area of the hospital and tell you to leave and never come back. There are many groups that have experienced this particular incident and I personally actually believe it is true. Maybe that voice I heard was actually tying to trick one of us to believing it was a group member and then make us follow it. Who knows. There are plenty of scary stories about the place that you can read about! If you dare ;)
