Spinning when feeling tense or overstimulated is a stare-worthy activity and may alienate those present.
Spinning is something I do a lot. Rocking is a typical autistic behaviour and, whilst I do rock, both are stims and fall under the umbrella of repetitive behaviour. I've also noticed that I spin a lot at train stations. Probably because it's so loud and crowded and there are weird smells, not to mention the
stress of getting the right train at the right time. There are just too
many things going on and spinning helps me almost to block out
everything going on. It's very calming for me, but apparently not for
other people. Several times I've been approached by others waiting on
the platform to ask if I'm alright.
