She replies that she is talking to another child standing on the stairway who is wearing pink shoes.

According to The Nation, Kru Ju Taksaporn Yodthong said that she had noticed her daughter, Im-aim, speaking while standing alone in front of a computer room on the second floor of the school.

When Im-aim said that she was talking to another child, Kru looked around and found there was nobody else there as all the other children had left.

The mother-daughter duo had been stranded by the rain and did not start to leave the school until dusk.

In the video, Kru tells Im-aim to tell her "friend" that their car was full so that he or she should carry on playing and not follow them.

When the girl turns her back to convey this message, a mysterious third person's voice is heard saying "Krub" which translates to "yes, sir".

The video has since garnered over 5.6 million views and over 60,000 shares since it was posted on Monday at about 7.36pm.

In response to comments from netizens, Kru said she did not know who replied "Krub" and that she did not want to see the owner of the voice as she was startled enough.
