6 Nights at the MAS Training School Accommodations

An ex-MAS staff, KL, once attended training at the MAS training school. She stayed there for 6 nights.

As there was nothing much to do, KL used to watch NTV7 movies late at night. The movies started at 11pm, and it was news time at 12am.

At exactly 12am, KL would hear strange sounds. She tried to listen carefully to the sounds, and it sounded like very very slow music sung in an unknown language.
The singing was very clear, but she was unable to make out the language even when she concentrated. According to KL, it was like "small kids simply singing, but with adult voices."
The sounds were coming from the air-conditioning vent.

KL called the receptionist to ask why they had turned up the volume of the speakers outside her room, and was told that they hadn't turned up the volume.
So where were the sounds coming from?

Then, the tv remote control went missing.
KL looked for it all over, and even moved the blanket and sheet searching for it. But it seemed to have disappeared.

She went to class. When she got back, the tv remote control was on her bed.
KL said it was as if "someone watched tv on bed then left the remote there."

Her trainer noticed her expression and asked why she looked so pale. KL's friend then told him that there was "something wrong" with the room. The trainer was concerned and immediately asked KL to change her room.

However, KL decided to remain in the same room as it was already her last night there.
That night, she heard the noises again.
KL called the receptionist and asked them to accompany her and find out where the noises were coming from, but they refused. They told her not to think about it and go to sleep.

KL's room was at the end, so she had only one neighbouring room beside her room. An Indian lady from Terengganu was staying in the neighbouring room.

Every night KL could hear loud sounds coming from the room besides hers. It sounded like people were purposely opening and closing the clothes cupboard door very loudly.

As there was a Kuala Lumpur-Terengganu flight at night, the Indian lady flew back to her hometown after the last class on Friday. KL stayed another night.
That night, even though the Indian lady had flown back to her hometown, there were loud banging sounds coming from the empty room...
