evil dream, scared!

[haaj]

Here's my dream went... someone help me interpret what in the world could mean.

My brother and I along with our friends are sitting in the hallway of our apartment building and theres a fan there that automatically turns on by itself. A little creepy but we didn't care. As it oscillates it will do so but then focus on my brother then turn again and focus on my brother. Then as it oscillates it moves closer to my brother. my brother notices and says that's really weird and we start laughing but the fan says "shut up" to him... we stop laughing and confused, i say "what?" The fan this time in a demonic voice says "I said shut up!" And I immediately woke up!
Never have I been so scared in my entire life!! What could it mean? Why was it only focusing on my brother?
My bro is going to miami today for about 5 days... could this mean something? Someone plz help me! This is really scaring me
