Ditto. I remember my first and only floater which manifested in a somewhat dark library. I found myself batting away at what appeared to be a rather large and persistent butterfly. Took awhile to calm down! I still haven't become accustomed to it despite my opthalmologist's assurances that my "eyes will accomodate" to it" (BS I think).
A friend of mine saw a floater for the first time and was freaking out. This confused me since, by then (and we're the same age), I was used to seeing the world through an aquarium of floaters. 8D
