I think a UFO appearing is a bit different than Barney or Unicorns farting dust. I mean, getting confused or spooked by a weird light could do it.

May I ask what makes someone blandly neurotypical? Having aphantasia isn’t something that makes you weird, it is actually really common and can occur naturally, or from physical or psychological trauma. Every person on this earth has a spectrum of what their mind’s eye can see or can’t. We have 5 different ways of thinking and only one of those is through imagery.
