What I Used To See

When I was around 7 or 8 years old I used to see things that I could not explain when I woke up in the middle of the night, my parents just wrote it off as night terrors however I do not believe that was what was going on because when I woke up each night, I was wide awake. I have decided that I am going to share something that very few of my friends know and my parents don't want to talk with me about because the doctor told them it was just night terrors. Ever since I was little I would wake up in the middle of the night and see things that I couldn't explain, things that would terrify an 8 year old, luckily I don't remember most of them but the few that I do just sends chills down my spine. One night after I went to sleep I woke up around 2 in the morning and I looked off of the side of my bed and for some strange reason I saw my teacher floating there glowing white, me having just gotten used to seeing things like that I turned around and as I did something that looked like either a multi headed dog or dragon came out of the wall at me. When it came out of the wall I just fell asleep for no reason just passed out, when I woke up I freaked out and tried to tell my mom and she told me that it was just my imagination. The bad thing is that ever since that night I have felt as though something has been watching me. I also used to wake up in the middle of the night having have had dreams that my parents were going to get divorced, well a few years later they did, If anyone could shed some light on what that was that I saw come out of the wall at me I would appreciate it. Thank you
