My teacher looks like House

I have a teacher at school who is just like House, with the same eyes, beard, height, apparent weight, hands, everything, except the nose because my teacher's nose is very straight. What is bothering me A LOT

The reason is because I've had erotic dreams about House, and very detailed dreams... looking at this teacher reminds me of dreams, and consequently because he's almost the same as House, I end up having these erotic fantasies with this teacher.

But to be honest, this teacher is a delight.

During class I keep imagining these things and I feel embarrassed by the agony of looking at him afterwards, and in class he focuses a lot on me... help
