Sleep Shuffle helps you fall asleep without deep thinking.
"Alexa, open sleep shuffle"
Then, this skill gives you comfortable music and random words. This method is derived from "Cognitive Shuffle" designed by Dr. Luc P. Beaudoin.
The comfortable music will be played for around 15 minutes and random words will be red for around 30 minutes. There are 150 words and they will be red twice each.
