Do you suffer of hallucinations ?
It is possible that you didn't noticed , but all danger of hallucination come to be not noticed as hallucinations but taken for real
A early diagnosis may help try to look at the image below , a slightly modified tartan pattern
is a static image not a animation so can't be flashing effects, sensation of lines moving , and obviously all lines are straights are not concavity or convexity
...if you even staring don't see any flash any slight movement any curve you should be immune to most optical illusion ...only risk for you will be go to see a movie , should be boring see 36 almost identical images flash every second instead while your friends are watching smooth cinematographic sequences ...and TV will be worst (just 1 moving line of pixels, the rest all created by a optical illusion, a commune hallucination...
)
But that is only one of the little prices to pay to not suffer of hallucination
