THE GHOSTLY HAR..

Sound like a heavy ghostly HAR..

It' was about 0230 hrs, I was awake, I slept on my right hand and was facing the wall.
I heard a very loud heavy ghost slight sound "HAR." but I did not turn back to look. The sound was just behind me.

I was with the SPI The Singapore Paranormal Investigators, I was on the top level of the suicide Tower known as the observation Tower in the PASIR RIS swarm with a blogger name IZ, I heard a similar sound "HAR.." it had the same tone. The sound came from just beside IZ right, I sat on the left side of IZ.

I hoped is not the same thing.
