He Definitely Snapped
Despite popular opinion, Bryce’s parents were (and still are) adamant that their son was not suicidal. They insist that Bryce loved them too much to voluntarily disappear like that.

All we know is that Bryce had been awake for somewhere between 24 to 72 hours. So, the sleep deprivation, as well as his abuse of Vyvanse, could have easily sparked a brain reaction that caused him to hallucinate.
Even though… come to think of it, that also sounds pretty unreasonable, considering how he passed all the sobriety tests and showed no signs of psychosis.
