If you know what page/ads is getting the clicks you should be able to detect why it is or is it much wider spread throughout all your sites? It could be you've gone up in SE rankings - if you've gone up considerably then google would expect more clicks. Google doesn't add clicks in real time (I don't think anyway) they are audited before being added so yours look safe to me. Lastly, I reported an issue to AdSense a month ago but have heard nothing since...
Nothing is wrong with your clicks it happens often when some targeted vistors come to your site they find links of adsense interesting and click on them were as the vistor who is not targeted vistors to your site will not be interested to visit those links and this time i think you got more targeted visitor on the day you got more clicks....
