feeling like I am going crazy

The scenario is always different but always involving these same men. I don't understand the meaning of this or why it's been happening. I wake up terrifed and it takes me a long time to go back to sleep. Last nights dream was that I was hanging out with friends in an old school, and my husband and I got into a argument, he walked away and I walked outside to get some air. I turned around the corner to go back inside the other doors and all these men were standing there with bats in their hands staring at me with their creepy masks on. I screamed and started banging on the door to let me in and then I woke up. People always say dreams have meanings but what does this mean?! Am I nuts.
