I think i saw you in my sleep

soo I've written before but, I'm really ready to get back on track and really make something good. the book itself will be a draco x reader here is how it will go!
y/n is a mysterious pure blood witch when she turned 8 years old there was an incident she unleashed powerful magic by accident. Unaware of the truth of wizardry the orphanage nuns sent her to kleinwood asylum for the violent and psychotic. five years later another incident occurred, that's when a powerful wizard was sent to collect the girl. When he arrives at the asylum he finds four dead and several broken windows. In the Middle of the chaos was a girl about 13 was what his headmaster told him, She was sobbing, apologizing covered in blood...
y/n heard a gasp and looked up to see a man. The man looked as if he were goth, medium length black hair and dark robes. He looked at her with pity although she was used to that she was told how sick she was every single day but, he spoke. "My name is severus snape i was sent here on behalf of my headmaster, Im a potions master and teacher at Hogwarts school of witchcraft and wizardry.... you are not sick girl you are powerful!" he spoke with determination and eloquence so she would know the exact situation. Before she could ask any questions, he came waking to her. Snape grabs her arm, pulls her up to her feet and in a quick moment... they were not in her cage anymore... the walls were tall and beautiful she thought. "Y/n" she looks over to see a desk and a curious old man and bird. He had spoken her name- how did he know her? she looked to the man that had taken her from that hell asking him with her eyes if he was safe to talk to.. snape nodded she turned back to the man that had said her name "H-hello sir.. why... why did you have him take me away are you both trying to tell me I'm not.. a- a basket case? powers? wizards? is this real?.. and even if it is i killed my nurses i- i didn't mean it i don't even know what happens i thought i was severely psychotic"
