What is the meaning in a dream of classroom

i find myself in an old high school. the school is huge, the building itself is square, it has 4 floors and a basement. the center of the building is open (picture the pentagon design center but with 4 sides). The building is Dark, it seems to be lit only by candles but no light source can be seen. the stairwells are located at each corner of the building and are massive built of old wood and marble steps. in my dream I am lost trying desperately to remember where my locker is. i cant remember where my locker is, I cant remember which class I am late for or where the classroom is. I know I am late and missing classes and I am panicked, running around each floor trying desperately to remember where I am supposed to be. The whole time I am aware I am not prepared for any class; no books or notebook. I have had this dream many times over the last year. I am 50 y.o. i am a Scorpio. born 10/26/1969

I was at school, and I had a difficult time finding my classroom

Teacher picks me up by the arms and holds me in front of the class. He starts screaming mean things about me and I am afraid. He warns me that I don't want to know what he will do to me if I return. Suddenly I am in the hallway. I walk back to that classroom. He tells me that he warned me. He backed me into a corner and pulled out a knife.
