I tend to panic and think I've lost my glasses when they are in fact perched quite happily upon my face. Similarly, the old 'where's my phone?' while it's in my hand; more than once I've texted my girlfriend asking her to call my phone because I've lost it, only to realise that I must be using something to send a text...
I suspect this one might be something everyone does at some point too: spending money you know you don't have. As a student I can't really afford to spend any more money than the bare minimum, yet I too often do. Sometimes it's because I can see my rent hasn't come out of my account yet so I think 'great, I have money' despite KNOWING that I won't in a couple of days and I really ought to ensure that I don't spend so much that I can't pay my rent.
