@giovannicuriel @Potatofox @elexia @erkhyan I learned that trick from Batman the Animated series:

"As Batman eloquently puts it at the end of that episode, “reading is a function of the right side of the brain, while dreams come from the left side.”"

I don't really encounter written words in dreams anyway, nothing appears in that level of detail, and it's mostly black and white. More impressions then photos.
