I was the only one that knew though, because I have a way of being more connected with spirits and such.
Therefore, I was a very scared and disturbed little girl, but I was quiet about everything for a long, long time.
Now my sister has the same thing as I do, so when she says she see's a "monster" I know what she's talking about, and normally there's an opressive feeling hanging around in a room after a bad spirit has left, but only my little sister and I know that.
