PREFACE: I am slightly autistic- I have Asperger's syndrome. I wonder if that contributes to these issues.

I have been obsessed and over-stressed by this math competition I have to take very soon. I am not very good at it; on top of that, I believe it is causing me very high stress to the point of disassociation and delusion.

Yesterday, just before bed, I worked for a very long time on practicing for the competition. I barely understood what I was doing, and spent a lot of my energy. That was a bad idea, since I created an extreme amount of stress. I suddenly became aware that I was deathly tired. I became convinced I would die- I was going to die in my sleep. I also became convinced I was in dreamland. Again.

My mind, when under high stress, tends to turn the most random noises into the scariest noises- scary voices, sounds, etc. I also have the tendency to become paranoid over the dumbest things- for instance, last week, I heard one of those emergency tests on the radio (they accidentally made a mistake and said, CIVIL DANGER WARNING). I must of missed them saying it was a test, because I then became convinced North Korea was sending a nuclear bomb. I then became convinced that I was in a dream and my family was not real.

Later that day, I couldn't find my brother and I began to doubt his existence.

All year, I was paranoid about going outside before 3:00- I thought I was going to be caught by police and accused of escaping school. I am actually homeschooled, so I get school done quicker. I am also 2 grade levels ahead. I tested 97% percentile on the California Achievement Test.

I am still worried about going outside - I'm afraid the police will not like me flying my drone around. Note: I do go outside, and I always become anxious.

At night time, if I had a bad day, I can turn shadows in my room into the scariest things inside my mind. That's not the worst of it. One night, I was convinced that there was a black-clothed ghost with a white face hiding in the corner of the room with an axe- for me. I did not hallucinate it, I just feared it. I went and got a glass of water, and the fear did seem to subside.

When I was younger, I was often paranoid about a chimpanzee that was going to kill me. I was scared of going to the zoo for years. I still am, a bit.

When I am under stress, I doubt reality and often fill in areas of my day that I forgot in my mind with dreams. This leads to me getting my dream-memories mixed up with real life. My dreams are extremely realistic.

Is there a scientific explanation for this, and is there a scientific name for this?
