No, what I meant is:
The Entity triggered the dream so he'd wake up late and go to the fair the same time Marle snuck out of the Castle, bumping into her, and getting his hands on the pendent.
If there's no dream, Crono wakes up in the usual time, goes to the fair (Neither early nor late, actually, at about mid morning), spends time, goes home, dosen't meet Marle, and nothing out of the ordinary happnes.
