You know when you have an unexpected bad experience (possibly a crime), and it's so shocking your mind blocks it out?

This is exactly what my mind has done.  A few months ago sort of a trauma surfaced in my mind, and it was when I was 12 having private tuition. My teacher was teaching in another teacher's house and the place was cluttered with stuff out ready to be used. I was struggling to write to the end of the pages in my exercise book (had a habit of writing to the middle and then beginning a new line), so she threatened to cut my book in half. Then, she went to the window and picked up a saw and with a smile on her face, held it about 8 inches away from my right hand. I began feeling terrified and just froze while she ignored how I was reacting/appearing.

Now that this awful memory has hit me, I'm thinking to make a police report. It won't leave my head.

How many kids whether 5 yrs old or 13 yrs old, would find it funny having a huge saw shoved near to one of their hands? Surely not many
