We had one that did that as well, but he was just dumb as nails. He would be laying down with his tail around him so it's at his face (looong tail). Then he would hit himself in the face on accident with his tail, this would piss him off so his tail would start wagging in his face. This pissed him off even more so he would grab his tail and bite it, but as soon as he felt that he would realize what he just did and start grooming his tail. Playing it off like he didn't just do something stupid, but was just grooming normally. He did this a lot, because he wasn't always the smartest of the bunch.

I've seen my cat do exactly this. Not very often, but it happens.

He's not a smart cat, but he does have a tail he can cover his eyes with for naps.
