I was trying to sleep in a motel at a conference last night, but felt weird. I felt dizzy and disconnected, just a weird feeling. When I woke up, there was a black floater and little dots in the vision of my left eye. I took a nap hoping that would help, but it is still there. I have had floaters for over ten years, this seems like a bigger one right in the center of my vision. Should I worry?
