Unsual Experience of Mine

I have never believed in ghost before. But, strange thing happened to me when I was about to go home from my fitness center. It was Sunday. After finishing my daily fitness routine I was about to have a real quick shower before going home. When I entered the fitness bathrooms, all the bathrooms were empty including the sauna. I had checked the sauna before showering. Because at that time I was about to have a sauna time, so the steam could relax my sore muscles. But it was around 07.30 pm if I am not mistaken. So I dismissed my plan. When I was taking off my top, I heard a shower running. I thought there was a person. So, I decided to check that out. I looked around but no one was there and the shower in the corner of the room was running. I just relaxed and turned off the shower. In my mind at that time I just thought the pipe was in problem or else. I walked back to my shower to continue showering. But strange thing happened again. That time was the faucet. I was just dead silence when I heard the faucet running. I thought people or the janitor was trying to play a not fun game. After froze for minutes in the shower and still in my sweaty outfits, I decided to go out and find a person. But still no one was there. At that time my mind was twisted. I was afraid yet curious. I turned off the faucet and thinking for a while. I just stood up in front of the faucet and looked at the mirror. And BOOMM... It was just my reflection and I flinched by just looking at my reflection. And again I just froze in front of the mirror and thinking " What was that though? Was that a ghost? Was a ghost trying to say hello to me ?". With that I shook my insane imagination about ghost, turned off the faucet and be gone. I picked all of my stuff up and stormed off quickly never looking back. That's unusual experience of mine.
