Dream About Monster School Scooty Battery

I went to school and as i entered i saw that everyone was getting one class each or max 2-3 girls in each class. there were only girls and I heard eveyone say that let's to go this class as this one is least scary. I didn't knew what to do so I also got into a room where there was no one and locked all doors and windows. Then I got a sheet of paper where there were questions of junior classes and the teacher told me that I had to learn them and in 5 minutes a moster will come and ask me questions and I had to answer them . If I wouldn't,the monster may kill me. Then suddenly I was outside that school and I was going home with my scooty, when a saw a friend (in real life I don't know who is she, but in dream she was my friend) . Her parents came to take her but she said that she'll go with me. Her house was just in opposite direction of mine , so I left her at the colony gate and continued my way back home. It was late night and I was going back to my house on my scooty when I noticed that my scooty is out of battery (i have an electric scooty) . Then the dream ended
