Get random spells on Oblivion?

I just made a new character on Oblivion and I was going through the whole tutorial phase and I keep getting random spells that I don't earn normally as i did with one of my last charecters. I made a Breton Mage and one time right after i loaded my game, I had like 3 new spells out of nowhere like electrifying touch. Is this a glitch or a normal buildup of a mage?
