I have been experiencing very scary dreams lately. For example, a male coming into my bedroom through my window at night to murder me. I physically struggle with a middle aged man and he is chooking me with his arm around my neck. I then continue to try to break lose and scream but i cant. No sound is coming out. I have no voice. I try hard to yell for help to my mom and sister in the next room but the scream is not loud enough to hear. I dont die in the dream, but I wake up scared. Then while awake I hear a loud scream by my hear inside my room...it was not a voice i recognized. I did sleep with my bedroom window open on that night. What is going on? What can this mean?
