HUNDREDS of people were left thinking a portal to another dimension was opening above them after this bizarre rectangular ‘alien doorway’ appeared in the sky.
Video footage of the strange “UFO” anomaly was posted on social media after residents of Jinan, in Shandong province, China wondered what was happening.
In the video, people can be heard discussing what it could be.
Some people commented online that it looked like some sort of portal was opening.
One online user said: “The door of heaven is open.”
Another said: “Above is a flying carpet.”
While a third likened it to a mobile phone in the sky.
It has since emerged through local reports that the light was probably from a spotlight projection being beamed onto clouds.
China has seen a number of strange apparitions in the skies in recent years with what looked like cities in the sky forming a number of areas.
They were believed to be the result of fata morgana which is a type of mirage.
