OS X V10.6 Snow Leopard :: MacBook Pro Shut Itself Down

My MBP just freaked out on me a little. I'd let the battery get pretty low, and had left the machine alone for about 15m. After plugging in, I couldn't bring it back up, and assumed I'd hit the hybernate point with the battery drain, so I hit the power button. Instead of coming back up from hybernate, it rebooted. Apparently it had arbitrarily shut itself down instead of going into hybernate.Here's where it gets really weird though: When it came back up, a bunch of stuff was ganked. Personal stuff like the finder windows I had open and my dock were fine. But my system clock reset to 01/01/2008, AirPort had an exclaimation point in the menubar icon and didn't default to my network or know my password. And upon login, I got three dialog boxes asking connect permission for three processes I'd never heard of. Unfortunately, I don't know the names of the processes because I F9'd to get a good look at all the dialog boxes at once (they were stacked), and when I hit F9 again, Exposé didn't close, so I tried ESC...which closed one of the dialog boxes! Hit F9 again, didn't work. Hit ESC, and another dialog box closed. Ditto for the 3rd one, and after they were gone, F9 finally worked for closing Exposé. But at that point, I'd lost all 3 dialog boxes. So with ESC being the likely equivelent of answering NO to the allow each of those dialog boxes was asking me about, I've now denied connecting persmission to three processes
