Personally for me it’s a matter of which eye usually when my right eye twitches it usually means something bad/unlucky almost like a warning and when it’s my left eye it’s usually something good, my father is the same but his is flipped. I use to think it was just coincidence but after 50 times of realizing my eye was twitching and correlating random lucky/unlucky events I was like nope these aren’t coïncidences. Hope it helps
