Insectile-related synaesthesia?

Hi folks, how is your weekend going so far? Julie's at work right now, but that's fine, because it allows other people a chance to shine on here. Mind you, today's special guest seems to be heading towards having a permanent support role, considering her output so far (here, here and here. The last of these has a permanent place in the top ten, it would appear).

Yes, once again, one of Sharron's daughters makes one of her special pronouncements. Special enough, in fact, that it prompted her mother to make a request on facebook for possible explanations...

For a little while, the meaning remained quite elusive. However, I think I have it - maybe it's all that time with Julie?
Basically, my reckoning is that Sharron's daughter saw this little bug and imagined it inside her shoe, wriggling around. And that she imagined it so well, she thought that she felt it. What do you reckon?
