A woman from Serbia views everything upside down because of a problem in the way her brain processes images.
Bojana Danilovic reads papers from the bottom up, uses an upside down computer screen and needs to work with topsy turvy forms in her job.
The 28-year-old council worker, who is suffering from the condition since birth, relaxes at home by watching one TV balanced on its top while the rest of the family watch another.
Experts from Harvard University and at the Massachusetts Institute of Technology said that the economics graduate is suffering from " spatial orientation phenomenon," the Daily Express reported.
Danilovic, who works in the Serbian town of Uzice, said that the experts say that her eyes see the images the right way up but her brain changes them.
She said that they don't really seem to know exactly how that happens, just that it does.
