my flashes of light, blue sparkles, dots spots are part of my having MS and migraines medication problems and psychosis (visual hallucinations) usually contacting my treatment providers and adjusting my medications take care of this problem for me.

my dissociative visual disturbances are things like seeing things and knowing whats real but feeling as if they are farther away or closer to me than they really are. seeing things that are really around me but not connecting that they are there. like knowing that coffee table is right there but end up stubbing my toe on it anyway because my mind was not fully aware and making a judgement of distance. knowing the floor is a flat surface but ....feeling... like it is tilting to one side or another. knowing the windows are stationary but.... feeling... like they are moving, warping in and out of shape like circus mirror does to objects.

my suggestion is if this continues bothering you, contact your treatment providers. they can assess whether this problem is a neurological\physical mental or normal problem for you and get you treated for it so that it doesnt continue happening for you.
