I took what I thought was cocaine but I'm pretty sure it was laced with something as we were all out of it. This was in March. During that I started seeing black dots in my peripheral vision. I still see them upon wakening and randomly on white walls. My other symptons are visual snow, after images, I've seen breathing walls, coloured specks and flashing dots. I have also seen like a smokey thing a few times. Benzos help prescribed by the doctor. I have extreme anxiety. My eyes have been tested multiple times and I am waiting for neurology. But if nothings found is this hppd? Especially when the dots started during the trip? My doctor just claims its a typical migraines. Oh and geometrical shapes and sometimes faces. If I knew for certain there wasn't something more sinister going on, I think I'd be less anxious. Anyone anything similar to the black dots and geometric shapes? Thanks, 27, female, mother (idiot I know) and terrified.
