are these CEV's?

[jwise]

well just so u know i havent tooken any hallucigens or anything.

(when i listen to them i lean over and put my face in my arms and press my eyes up against my arms) ok so when i took OPIUM and Marijuana i started to see these strobe lights flashing.... its so awesome.... well anyway and then i started to see collorfull circles/bublles just passing by me like i was moving. then on another dose witch i forgot which one (i think it was opium) the sound remined my of a storm rumbling and a car passing by. so this picture popped into my head and i was right below a cars trunk looking at the whhels spiinning on a farm road.

are these CEV's?

Thoughts, may some say. : ) Something as detailed as the farm road might not count as CEV's, unless it was way more intensive than just everyday visual thinking. Did it feel like having a dream while being awake? Or did you fall asleep?

Was also curious about CEV's too so here, I saw a wiki http://en.wikipedia.org/wiki/Closed-eye_hallucination
