I was sick the night of 12/20/12 with bronchitis, so went to bed around 6:30. I took an ambien, which I have on many occasions with no adverse side effects, so that i could get some rest in between the coughing. At about 12:30 am, 12/21 at this point, I got up to use restroom & when I looked in the mirror I almost scared myself because my pupils were so huge & black. I have tripped many a times on acid & mushrooms, but never had my pupils even close to that dialated & i have never seen things that weren't there, aka hallucinations. Well, after I went back to bed, I couldn't sleep so staring into darkness of room, I started to see the craziest things forming in the light particles & moving, coming towards my face & then always changing into something else and moving away. When I went outside to get some air bc it was freaking me out, I looked up at the stars & there were the white lines in between all the stars, showing the grid of constellations, clear as day. Mind u, I took an ambien at 6:30 & now it's bout 2:45 am . So needless to say, I think there is something to this post, when & how it will hit you & effect you, no clue. I say ride the wave.
