This is a theory as told to me by Mr. Dan Lima
“As per the meta-physical elctromagnetic anomalies that occur on the island causing frequent para-dimensional occurences, it is quite possible that all the characters themselves (judging from the flashbacks) are all confined to a limited area, possible Locke’s backyarad, all attending a saturday afternoon BBQ, and are all experiencing halucinations due to drug enduced brain activity. Basically, they are all in Locke’s backyard trippin’ on Acid.”
