Pictures show the spirits of soldiers in Singapore

“They are datuks, guardians of the river.”

A photographer in Singapore unknowingly captured a rather eerie scene.

Thomas Tan, who said he was taking photos of the fog that had moved into the Sembawang shipyard on the north part of the island, noticed what look to be human figures standing in his photographs afterwards.

Tan was out around 10 p.m. on Oct. 3 and says he was completely alone, in a Facebook post that has gone viral.

“I was all alone, there wasn’t a single soul when this photo was taken but look at the image carefully again,” explains Tan in his post.

“This isn’t edited and it is a raw photo,” he wrote.

Many people are commenting on the post, noting the figures look like soldiers or sailors whose spirits are guarding the area. One person commented that the spirits enjoy coffee, recounting that if you stir the coffee for them long enough, they will place a precious stone at the bottom of your cup.
