They're everywhere

Through the past week i have tried my hardest to find optical illusions around me. Trust me, theyre hidden everywhere, you just don't realise it. One of the most common ones i have seen while doing this 'mission' are multiple meaning illusions. It didn't surprise me, i would have expected it. Because, even now, im staring straight at an illusion, i just cant see it. If you want, you can conduct an experiment like this, too. P.S. sorry i didn't tell you guys i was doing this):
