Thanks @nomad-magus for yet another great interpretation.

Like the dreamer and you rightly said in both the he dream and the interpretation, dreams like this always have things to do with emotions

Myself as an example, their was a time I kept dreaming about having sex in my dreams, but it used to happen each time I imagine having sex in the physical. When I think about sex too much during the day, I will see myself dreaming about it at night.

Probably, you think of having such a wired sex before you sleep, that might come together and manifest in your dream.

Like Mr Magus used to advise, tell yourself what you would like to see or do in your dream when you want to sleep, it has a lot to do in overcoming such a situation.
