I had this dream several times, at first I though it was just a dream but now, I always have it once or twice a week sometimes my brother in law chases me with a saw trying to kill me

It is a dream, you seem fixed on it, is there a reason you feel threatened by them?

But, in the dream world, normally a dream means the opposite of what you dream

Also, what goes in is what comes out? What sort of television are you watching?
