I find that I have a general lack of awareness of what is going on around me and do things on 'autopilot' a lot, for example back in my uni days I remember walking in one morning and nearly getting run over by a car, I'd just pretty much crossed the road without looking even though there was blatantly a car coming. Shook me up quite a bit but then 5mins later I realised I was crossing another road without looking :/
Another thing I've done when very tired was to go to a cash point, ask for £40 cash, retrieve my bank card and then just walk off after putting it back in wallet without taking the cash. Didn't even realise until I checked my wallet later.
I also find when deprived of sleep it moves up the list of priorities a lot, in terms of wanting to go to bed. I know that sounds obvious but I'm talking about starting to act like an addict who needs a fix, going to great lengths to be able to sleep and forgoing other important things, not being worried about how much it costs. I've lied to family before in order to be able to go to sleep before after 52hrs awake.
