Screamed When I Was Asleep

Something awful happened to me two days ago. I was asleep but woke up suddenly and screamed when my brother entered my bedroom. My brother appeared to me like a very evil and scary monster when I awoke my from sleep in a very sudden manner. I do not think ghosts are very important since they are from the Devil. However, I was not in a very good mood a few days ago. I just don't know why I got to awake from my sleep and screamed like an animal. Apparently, I had not slept with one of my powerful weapons. As a Christian, I pray to God when I am about to sleep because He has the power to stop the Devil from causing actual havoc to me.

Do you get scared when sleeping in your own bedroom? I am not a sissy but I have been screaming in a very bizarre manner lately.
