A video of an empty seesaw, at a HDB estate, rocking back and forth as though children are riding it has been going viral online.

The video, which is shot from a distance, first shows a long shot of the empty area around the seesaw, that makes it seem unlikely that someone set the seesaw to rock before moving away.

As the camera zooms in, it is clear that the seesaw is quickly rocking back and forth and does not stop or slow down significantly until the video abruptly ends:

Ghost month funny thing happen

Posted by SINK – Singapore Ink on Sunday, 19 August 2018

Although it is exactly unclear exactly where or when the incident occurred, the video quickly garnered thousands of views after it was shared on social media this afternoon.

The video also appears to have alarmed some Singaporeans who have pointed out that the incident appears to have happened during the seventh month.

In Chinese culture, the fifteenth day of the seventh month in the lunar calendar is called Ghost Day and the seventh month in general is regarded as the Ghost Month, in which ghosts and spirits, including those of the deceased ancestors, come out from the lower realm.
