Prazosin works very well at stopping nightmares. Our brain is more complex than anybody will ever understand. Who knows what is is. Normally though if we do dream about other in our sleep it is about other aspects of our own selves. Maybe your mind is trying to alert you to that fact that something is off and that is needs taking care of. Maybe a part of you is scared and calling out for help. Something to ponder.

I often wake myself up by taking loudly.
