If I have too many things to think about in my head I sometimes have a sensory overload like that and I usually rush around tidying up or trying to put things in order, to calm myself down.
If it's a sensory overload caused by too much visual stimuli, too much noise, too many people etc (this will often happen when I go clothes shopping - an activity I really dislike) I usually go the opposite way and became tired, weak, dizzy, light headache etc... when I get like this I just want to go underneath my duvet.
I suppose the first one is more of a meltdown and the second one a shutdown.
