Actaully i've had an E flashback once or twice. it was a nite that i was heading out to a club but decided to go it sober. But on the train listening to my md player i just fell into the music then my leg started tingling then my whole body stayed like that for a couple minutes remembering nites i had rolled and just tingling all over bobbing to the music. this kid next to me. say me zone so he just gave a smile nod and was like have a chill nite. but E- flashbacks are possible
