"Yes." Senku said, nodding. "I've woken up enough people to know that they are. How long they remained conscious may have been to about ten days for people with mental fortitude, but every nine and a half days or so your consciousness really tries to drag you under. I remained awake the entire time, as did my friend Taiju, but everyone else had no idea what happened really. They saw the light and then woke up in the future."
