Sometimes people with autism start laughing like a hyena or appear to be having enormous fun on their own without any obvious reason for it. You must be wondering, What on Earth’s gotten into him? At times like these, we’re having “imaginings.” Or not quite imaginings, but we experience pictures or scenes in our minds that pop up out of nowhere. Maybe it’s the memory of something that made us laugh, or maybe it’s a page from a book we read.
