An Unidentifiable Picture
This is an optical illusion of extraterrestrial persuasion. Many stores and restaurants have clear windows as a marketing mechanism. They let visitors peer through, coaxing them to enter. However, these windows are so reflective, you may see a lot of people use them as mirrors. They pretty much reflect all objects.
As this person was dining, they noticed that the ceiling lamp inside the restaurant was reflecting off the clear window, causing an illusion that there was a giant UFO with a big purple rim coming closer to earth to make its landing. It’s interesting to see what just a simple reflection can do.
