Skyrim does strange things sometimes, but is this normal or just a weird glitch I've managed to stumble on?

Alright, gamers, so I'm playing Skyrim, right? And I just completed the "Blood on the Ice" mission and take a merry little trip onto Calixto's place for a nice looting, where, naturally, the first thing I do is use his key to unlock the chest. I pick up the "Butcher's Journal" just fine and dandy, read it, and put it into my inventory all peachy keen wonderful.

The weird things start to happen when I try to read it from in my inventory. When I go from my inventory, instead of displaying the text, my character goes into an animation as though it were the Elder Scroll, where she pulls out the paper and the same natal-chart-type pattern and a few seconds of a blurry, similarly patterned fish-eye, bubble type lenses.

So I have a few questions here, really.

A.) Is this supposed to happen? I don't think it is, but I might just be forgetting something that explains it away.

B.) And given that it is not supposed to happen, does this happen often to people that you know of? I did a search and I haven't run into anything to the extent, but again, I might just be missing the obvious here.

And C.) For anyone who may know, do you think it will effect any other part of the game to have a retarded, butcher diary Elder Scroll in my inventory?
