Hexagons when you wake up

Recently, I have noticed something new(At least ive just started to realize it) and strange..

Whenever I open my eyes for the first time in the morning, or do that quick "look at the clock close eyes again".. My vision is turned "Hexagonal" Kind of hard to explain.. but it reminds me of what a flies vision is always portrayed as.

With lots of different sections..
Very strange but only lasts for a fraction of a second.

For instance, if the first thing I see is the ceiling, my vision will be split up into many small (and rough, without well defined lines, kinda blurry) hexagons. Going in a checkered pattern, where some (not necessarily following an exact checkered pattern, maybe a little sparser than that) of the hexagons are darker than those around it.

Just wanted to know if this is a universal thing, or if its just another "FREAK" thing to add to my freak list

EDIT: I recently watched a lasik-surgery thing on TV.. When they pulled back the ladies eye-whatever, the pattern underneath was alot like what I see..
*looks for a picture*
