Screen changes by itself?

I was just surfing the web on dolphin hd (droid-life and gizmodo) and while I opened new tabs, the phone clicked on random links by itself and when I tried to press back or pull down my notification bar for task killer, it wouldn't do so, so then I went to the home page and it would click on random icons such as google talk or google voice which would require me to go through app lock and it just bypassed it and went to the password settings, and by then I took out the battery. Any reasons as to why this might happen? It hasn't been doing it since..
