one thing that really helped me during WBTB (it was the first time it actually worked for me) was when I wrote down everything I needed to remember. Like usually I would fall asleep saying "I'm going to know I'm dreaming" "I'm going to remember to do a RC when I see my dreamsign" etc. but just before I fell asleep I wrote it all down, and then it was easier to keep in mind as I was falling asleep. Except I dont know how that would help with keeping you entertained, but it helped me
