Anyway few things more.
I've done a research on the people that lived in my house before me, there was an old woman that died in there like a year ago.
Now, my little brother has this robo toy, so he played with it in my room and left to sleep, as he left I started to play some games and the toy was on my table, then I looked at the toy for few seconds and back to the monitor, as I look at the monitor suddenly the toy starts to play its shooting noise(I didn't touch it, no wind, table didn't move, NOTHING), so this toy has a button on its back, few seconds after that and the toy still plays the sound so I took the toy and looked at the button, and it was pressed.
