A Reddit user with the nickname "adamgriffith01" posted a video of a surveillance camera in his apartment and asked him to explain what it might be.
According to him, in the place on the video, where the intense glow was filmed, there are no light sources, except for the usual lamps at the top, which are turned off, including no computer and flashlights.
Also, there is no electronics at all.
The video shows that a strong glow appears in the background itself, as if its source is directly on the surface of the table.
The effect can be compared to a cinematic special effect, when the hero of the film opens an enchanted book and streams of light begin to emanate from there.
This was filmed between 3 and 4 o'clock in the morning, and during this time this incomprehensible light source twice turned on and off by itself.
In the comments, users first suggested that a smartphone screen could have such an effect, but the author replied that there are no smartphones there, except for one, which its owner always carries with him and keeps next to him by the bed at night, and not at the specified place.

He also noted that it is unlikely that the screen of a standard smartphone will give such a powerful light.
According to another version, the camera filmed a certain energy source that is visible only in a certain spectrum, for example, in ultraviolet or infrared radiation. And its source could be any electronic device within the house, a WI-FI transmitter, Bluetooth or something similar.
There have been suggestions that this is due to the refrigerator, but the author said that the refrigerator is more than a meter away from this place.
According to another user, this could be the reflection of the headlights of a car from the highway. However, the author said that the window of the room overlooks the backyard of the house.
Other users agreed that this is definitely not a ghost, but some kind of physical phenomenon, but which one is not clear.
