Does anybody else get this? The best way I can describe this is that in darkness I get a visual snow akin to that displayed on an old television set; though the colours generally consist of red, yellow, blue and purple. The dots which consist this image seem slightly larger than that of the usual static created by a television set. It kind of appears like what I'm seeing isn't a high definition image. Instead every colour is preceded by a faint background fuzz, consisting of the aforementioned colours. This fuzz appears to be somewhat vibrating, although somewhat slowly. This first appeared when I started smoking weed when I was about 16/17. I know about HPPD, but I'm interested to see how common this is. Anyone else experience this? It can be quite overwhelming in a dark room.
