Dream About Mother Beating Me To Death

So, I dream that I was beaten to death by my Mother... And police and officers are getting involved.. and I was asking them for help and so while I'm crying, My nose is bleeding and I'm very likely wounded and bruised. Luckily there is a witness that's willing to testify and that... Telling them how they saw my Mother acting strange and like there's these weird sounds like tiptoes and that... And so she follows her into a room and that.. I also dream that I failed to pass this school year because I have "one blank grade on the card in a specific subject" And that I need to go back to Elementary from the first year graded just because of that one blank grade... So, I was in the classroom with teachers and students from the first year...I was sitting quietly and the teacher was doing her discussion and that.. After class, upon walking around the room... I was feeling frustrated and confused... Because, I don't seem to understand why I would be sent back here in elementary just because of that "one blank grade" Although, I already thought of the benefits of it.. of me being in the first graded and that I will learn all of the basics again and use it to my advantage... I can't help but feel frustrated and ashamed... because of the time I've calculated and that... So upon observing students chatting and interacting with each other... I go to my drawer, get a thing or two.. maybe a charger and a cord or whatever it is..Then, I walk out of the room never looking back. Then, I've heard as I was walking to the unknown that my grandmother was looking for me and that to streets and so.. Then, when we finally met.. there's the voice of narrator again... Describing her into my standards and that... Like she has a long hair, in a light dress and she has an umbrella leaning to her neck wide open...
