Four years ago, my family and I went on a family vacation to Singapore. Since we were a large group (my family has 9 members, and my cousins had come along as well, together with our parents), the parental units decided that it would be more economical to rent an apartment instead of a LOT of hotel rooms.
The apartment block we rented was pretty nice, modern with maintained facilities. I forget the name though.
Anyway, on our first night there, one of my cousins, together with my brother and I decided to find us a little adventure. By this time, most of the shops were closed, so we decided to just explore the apartment block. We hadn’t had time earlier as our parents had scheduled a full day of touring and we had been out shopping until most of the shops were closed.
After wandering around for awhile, we got to the swimming pool. It was a windy night and we could see the ripples on the water, because the spotlights of the pool were nice and bright.
We hung out there for awhile, dipping our fingers in the water to test its temperature. Cold! After a few minutes, we got bored so we turned to leave. That was when we saw the wet footprints leading from the pool to the exit! They were not there earlier, we would have noticed. All of us were wearing some kind of footwear, sandals or shoes. No one had taken theirs off. And there was definitely no one swimming around in the pool the whole time we were there! If we could see ripples on the pool, we could definitely see someone in the pool.
We had a small but furious discussion to confirm that no one had seen anyone leave the pool. No one had seen anything. Deciding we had enough excitement that night, we decided to go back to our respective apartments.
Carefully not touching the wet footprints, we followed it to the exit. The creature that had made it (human or not) had apparently taken the elevator. The footprints led straight to the single elevator. When we went in the elevator, the floor was wet.
Needless to say, we were very very quiet on the way up to our rooms and just went straight to bed.
