The dream
I'm 20+ years old. I had a dream that I was in boarding school (at the dormitories). Basically, in the dream, I'm at university and not a child.
The most striking part of my dream was that close to the entrance to the room there was a hole in the floor, and I saw through the paving some soil that had holes in it. I realized that there were mice under the tiles and I went to the room of the maintenance guy. Eventually, there was a woman there who took on herself the extermination task. She found another hole and we heard squeaks and knew it was proof of mice. In the end, I also saw the head of one of them.
In the dream, it was important for me to get rid of the mice even though in reality if we find a mouse in the house we take it humanely and release it to nature.
For what it's worth, I finish studying (design) this year and I am alone now. I live with a flatmate and everything is fine. I'm a middle daughter, I have characters I admire - but not total admiration, especially in my family. I give advice to friends and get special advice from the family
My Interpretation to your dream
The dream begins with the fact that you are in school, that is, it is a dream that wants to convey some message from your higher consciousness. It's a pity you did not describe other elements of the dream, but I will relate to what you wrote -
The mice seem to represent doubts, hesitations, fears - perhaps about relationships, maybe a career ("What will happen after I finish school?") You try to find solutions to your doubts and invite your mind (= male character, the house maintenance guy). But in the end, it is actually the female energy in you (a woman who took the job).
The message here is clear - trusting the inner woman, not thinking too much (certainly not worrying), trusting your intuition, your inner self.
