Actually helps. Everytime I read the dictionary before I WBTB, 99.99% of the time I dream, I remember more then 75% of the dream, and I usually realise i’m dreaming but I instantly wake up…
Do you mean our Acronyms dictionary or the real dictionary . . like a “Webster’s dictionary.”
If it’s a real dictionary, What letter do you start at?
and how long do you stay on the same letter? What’s your system? 
The real one, I usually start around letter D. Try and memorize words, and with the letter D especially, and sort of memorize rhymes with the word Dream. One of my favorite pastimes is going to dictionary.com before I sleep and putting dream into the thesaurus
