Do you get mad at people for events that only happened in your daydreaming?

I do this all the time and think, if we did this together you would end up doing that and that would make me mad, then you would do something to add on to that anger , and THEN it just goes on. To the point where I get so mad at this hypothetical situation that my eyes are water and my heart is pounding and my hands are shaking. Its crazy, I gotta stop it because it is a waste of mental energy and space.😡
