So I already knew that one is able to read and write during a lucid dream and it could be as vivid and as clear as real life. But having a personal experience of it was just amazing. Last night I had a lucid dream where I can see and read English text as clear and as vivid as I would in real life. Couple nights ago I also tried writing down things in a lucid dream and it worked and it was clear as well. What I was writing down exactly were things I would want to remember after I wake up from the lucid dream.
Anyways, I wanted to share my personal experience of this with everyone.

Tl;dr: I was able to read and write in a LD and it was as clear and as vivid as real life.
