Perhaps some of the music or effect sounds in Terraria are similar to those in the Red Robin advert, and it's triggering the memory. When listening to some heavy/metal music I think I hear someone (usually my mother) shouting for me all the time, even when she's not in the house. The shouted lyrics and such trigger my typical reaction to someone shouting for me; as soon as I notice what's happening, the effect leaves. It's not unusual, don't worry about it.
