is my dad cranked up on speed?

Hi today I was in the kitchen of my house after school smacking together a peanut and sardine sandwich when my dad came into the house and he seemed a bit odd, his eyes looked a bit red, and when he saw my sandwich he said something like "Make sure you don't choke on the ******* sardine bones, I don't need to go to my son's funeral because of a goddamn fish". My dad is not normally a worrier so I found this very weird. Why Would he start thinking about my death just because of sardines? This is when I suspected he was on speed.

Later on me and my mother were watching the biggest loser UK on tv and he came into the room with a knife sticky taped to the end of a broom stick and cut all the cords to the tv and turned off all the lights in the house, then he opened all the windows again using the brooomstick and staying away from the walls. He told us to stay away from the walls and to sit still, then a lot of tiny bats flew in the windows and came into our house. My dad went to his office and got a quadruple barrelled shotgun and started trying to shoot the bats and he was screaming ofhhh my dear he was screaming it was so incredible, he was agitated in extremis. He shot my mother in the stomach because he thought she was a sexy female police officer. Does this happen when speed junkies get their fix of speed? Crack Cocaine?
