Seeing things

[JackdawAquila96]

I see things in the corner of my eye, but at night I can see them in front of me even when I have a light on. In day time it's occasional movement in the corner of my eye when I'm alone, less when I'm with people but I have experienced it amongst people. Usually during the day it gives the same feeling like I'm seeing an insect in the corner of my eye, but it's not because nothing's ever there. At night I see full figures. Even since I was 5 I've been seeing a dark haired little girl whose eye change colour depending on the light in the room. She is the only one to have followed me to a new house, I don't believe in ghosts which was my mum's explanation, so I came to ask what's wrong with me.
When I'm alone I hear things downstairs, sometimes I'll check it out, I'll see a person with long brown hair & they'll be making a cup of tea. When I check the kettle afterwards the water has boiled, however since I'm alone I don't know whether it's another trigger for my memory loss since I get dissociative amnesia during high stress moments. The other hallucination is after I brush my teeth at night I go to leave the downstairs bathroom & a girl I don't recognise in a gown jumps at me and I physically stumble backwards. No one I know owns gowns since most the elderly who wore them died years ago. Again I know I'm drawing a lot of parallels, but I wanna stress I think I'm seeing things, in a lot of detail, but still seeing things, I'm not superstitious like my mother. I also keep dreaming that I'm dying through suicide, but I'm not suicidal & I can never see more than a shadow in the dream, I have a very specific clothing combination which makes it obvious it's me.
Full medical detail. I was born with suspected frontal lobe brain damage, I wasn't diagnosed until I was 19. I say suspected because I've never had a brain scan to confirm. I have problems verbally communicating, I have dyscalculia, dissociative amnesia, PTSD & ASPD. There is a history of alcohol triggered schizophrenia & alcoholism in the family, however I am not alcoholic. From my mum onwards in our family we don't like alcohol, the alcoholism stopped at her parents. Schizophrenia is still possible, just ruling out alcoholism before it's suggested.
When I was 4 I never responded to my name, I was almost diagnosed with hearing loss until my mum rattled food which got my attention through a brick wall. I am actually hypersensitive, neither deaf or blind. I have been misdiagnosed with autism & anger issues before, however it was dismissed as a wrong diagnosis because I can understand social queues even when I don't use them to respond & I'm docile until someone pushes too far, then it's a very quick outburst & I'm calm again.
Essentially these are my current diagnosis, however take them with a grain of salt because as you can see I've been misdiagnosed before.
Please, in your expertise what could be wrong with me aside from my current diagnosis.

I don't think it likely that you have a single thing causing all those symptoms but likely there are multiple causes.  A person with those symptoms needs;  1. to see a neuro-ophthalmologist (not a regular ophthalmologist, you may need to go to a medical school to find one) They need to do certain special tests including visual field and macular and nerve fiber layer OCT.   2. You need to see a neurologist. Likely they will want a MRI/MRA of the brain and an EEG to rule out atypical seizure disorder.  Depending on the findings of these two special types of MD's they may want you to see a psychiatrist for an assessment. Only when you put all of those together are you likely to determine the cause, and possible treatment of your problem.
