I had that happen for several weeks straight once. I had a dark spot under the one eye where it twitched. For me it was due to medication but, yes, stress and anxiety can definitely cause it and tiredness may as well.

I get the same twitiching under the eye but it's usually only when I'm stressed out.
I used to get twitching a lot, now its only occasionaly. But I would get it in my eyelids, under my eye, my cheeks, my chin, the corner of my mouth, and then my shoulders, sides, legs, arms etc... Its anxiety though.
