If i had looked in the mirror I might have been quite white. Is that what it means?

Yes, you can turn white as a ghost with nausea and feel really really really bad all over. Totally lose all color in your face. Can't really harm you, but it can feel like you might die....
Water and sugar are your friends if it happens---quickly drink both. Amsterdam coffeeshops quickly get folks with a whitey a sugar coke or sugar fruit juice to help.
How do I know this---
Amsterdam 2014, by myself in Paradox Coffeeshop with some really strong Amnesia Haze and like
@Skyscraper said, it can have a psychedelic effect. Had a Volcano with that HUGE chamber. Loaded about 5X my usual micro load and budtender looks over and gives me a " pffft, put some weed in dat chamber" and "the look" signifying you f-in pansy. I responded that I'm a real lightweight BUT double+ my load. So 10X + my usual load.
Two bags later, while blowing the 3rd bag I tell the budtender that I feel really really bad. Totally incapacitated for 2 hours and debated calling for med help. When you feel that totally shitty, the psychedelic impact makes it worse--- I was hearing all dozen conversations going on at once and tripping/ bad tripping.
To complete the bad trip, as I peer up from the couch where I'm prone, I look out the front door and it slowly registers---- that's MY BIKE that someone is hunched over, trying to unlock/steal it so I force myself to run out and chase them away.
You can ride out a whitey BUT it's not much fun and a waste of good bud
