Let me count the ways...
As an infant, making "wringer-type washing machines" (at least they were supposed to resemble washing machines) out of Lego. Ironically, I was terrified of the wringer washer at a family friend's house for some inexplicable reason.
Running my index fingernail down one side of my teddy bear, whilst saying "Strawwwwwp" - often followed by tossing it up into the air whilst exclaiming "Toossie!" ("oo" as in "foot", not "boot").
Drawing car dashboards in detail (although not precisely to scale). In small-town New Zealand in the late '70s/early '80s, people would leave their car doors unlocked; sometimes I'd peek inside their car without their permission to study the instrumentation.
Having a pathological fear of seeing a chimney cowl suddenly move (obviously due to a change in wind direction, although that didn't occur to me as a young child). Likewise, fearing using unfamiliar bathrooms, in case the toilet flushed too loudly, or a near-deafening electric motor somewhere started up ( I'd assumed it to be some fancy flushing mechanism; I now know it must've been hand-dryers).
Hearing the phrase "You're hanging around like a bad smell", and, without understanding its meaning or context one iota, visiting our elderly neighbours across the street and saying that phrase in front of them, simply because I liked the sound of it.
The sound of a music box made me cry.
At the end of grade three, the teacher had the class over at her house right next to the school it belonged to the education department). She handed out "noisy balloons" to all of us. Well, I was utterly TERRIFIED of them! Kids were soon letting the air out of them - EEEEEEEEEEeeeeeeeeeeeeee - to scare me.
Near the end of grade four - my last year at that particular school - telling other kids the grassed courtyard was going to be converted into a tarpit the following year, purely out of my imagination.
