Depends on the dots i guess. If its more like "sparkles" then yeah, I used to get that sometimes or if its like the dots you get from a camera flash that is normal too.
but if its like pink and purple poka-dot flying around then...no
A lot of the times when I get up (sober or not) I see sparkly purple spots for a few seconds, but I think that has more to do with blood circulation ^.^ that might be the case with you?
I'm pretty sure what you get is normal OP
