Absolutely man. 24/7. I get negative after-images a lot when I'm walking outside in the day time. One of my more frequent experiences is when I look at the top of a tree line, there will be a negative image of the entire tree line floating above the actual tree line, if that makes sense. But I would say anything that I look at for more than one second, if I look away, I will see it in front of me for a few seconds before it slowly dissolves. It's become so normal for me at this point, but there are days when it wears on me. You aren't alone man!
