why did claudia take fingers and breasts from that woman?

Hi, so I was rewatching the series and I think in episode five we see that Claudia is trying to make another vampire out of it. While she was trying to hide the pieces of the people she killed, it was possible to see several fingers and a woman's breast, but I was wondering why she took the fingers and breast from those people. Another question, when we see her with the police officer, she seems to be so drunk that when Loui tells her to go to her room, she ends up tripping. She was laughing at everything. Can anyone explain?
