really odd patches

today i had gotten my first lucid dream through a dild :boogie: but when i realized i was dreaming and attempting all these things, i also noticed that parts of my vision ended up with these purple..things sort of like this picture in the link http://www.geocities.com/tokyo/sprin...images/000.gif (not the pokemon logo part)
they randomly appeared but everything seemed fine other than falling for some reason when i tried spinning too prolong the lucid control, other than that i seemed too have full control over what i could do but can anyone explain these odd patches in my vision?

Probably HI coming into your dreams. Either that or it's the pattenrs you get when you do funny things with your eyelid. :)
