Dream About Being Trapped In School At Night

When I was younger I had had a dream where I was as usual in a school but it was the end of the day and it was very dark outside and I was with my two friends we were about to leave out to the school and when I came out it was pouring rain I had forgotten my umbrella and I told him just to go home and I ran back inside during when I was having this dream basically I was younger like in Middle School so I had seen my art teacher Miss Baker and my dream when I came into the classroom to get my umbrella she had told me that I can't leave the school I was saying what so many times because I didn't understand what she was talking about why couldn't I leave the school it was dark outside and I needed to go home but then she grabbed me by both arms and looked me dead in the eyes and say you have to stay here she didn't say anything else and just grabbed her umbrella and walked out of the school but before that she had put me into one of the rooms it looked like a room for elementary schoolers with colorful carpets and pattern walls with stuff on it I kept trying to push past her because I wanted to go home but she pushed me on the ground inside slammed the door and locked it and told me from the other side that I couldn't leave until the morning and she told me whatever I do don't look outside this window and then she left for the night for some reason I became very anxious and nervous and I was getting extremely scared because as soon as it hit the middle of the night I was hearing stepping I was hearing walking running and it the whole school was Pitch Black all I heard was children's laughter it was creepy I didn't want to look outside so I just started crawling in the corner curling up and crying and then when it became morning I woke up Suddenly from my dream
