I wasn't near Barstow but this pattern matches something I documented here in Appalachia back in 2019 almost exactly. Witnessed unusual lights, then found myself with roughly 2.5 hours unaccounted for. What strikes me about your account is the quality of the missing time - was it a clean break, like a edit in a film, or more of a gradual blur at the edges?
A few things worth considering:
Physiological markers - did you notice unusual thirst, skin sensitivity, or disorientation in the days after?, Electronic interference - any devices behaving strangely? My old Garmin GPS completely reset itself after my 2019 incident, Dream disturbances - fragmented, unusually vivid dreams in the following week are commonly reported
I've been cross-referencing these Barstow reports with some older MUFON case files and there's a cluster of similar accounts from that corridor going back to the early 90s. The missing time element appears consistently, which to me suggests this isn't random - there's a mechanism at work, whether that's interdimensional overlap, screen memory implantation, or something we don't have proper language for yet.
Have you considered regression hypnotherapy? I know it's controversial in this community and the evidentiary value is debated, but combined with a proper timeline reconstruction it can at least surface something to work with.
What was the approximate duration of the light sighting before the gap occurred?
