Hi.. I have this problem also. It started around 6 months ago. Woke up one morning to see 2 black dots upon the white wall which disappeared when blinking. I contacted my gp and have had 2 eye tests including dilated pupil and both say eye health is good. I am now suffering with sleep and hallucinations as I am looking for thses dots continously. Sometimes when I wake in the dark they look like spiders crawling up wthe wall.. Again these disappear when blink or changing light. Sometimes I see patterns also. I am not sleeping due to all this and feel is making me ill. I have lots of floaters and my eyes seem over sensitive in bright lights. I also get lots of copy imaging when I look at anything bright.
