I keep dreaming about my student teacher but I don't fancy him?

"I looked it up in my dreamer's dictionary and it said we were going to have a love affair." If your dictionary actually says that, throw it away. It is very common to have ual/love dreams about people u actually don't even fancy in real life. It doesn't mean u secretly want them or that something is going to happen between u two, it's just a random dream about love in general, possibly because u need affection at the moment.
