My friend Erin tells these wild stories. Should I believe her?

She says she had a drunken and did it with a girl and how good it was. She said she was attacked by a kangaroo when she was walking. There are plenty of kangaroos here for sure so that is not so far fetched. She said she got back from drinking with her friends and saw a space ship. She says other stories that are wild and far fetched. She says she drank so much one night she ped out and had a security guard kick her in the stomach telling her to go home and that she fell asleep at a family restaurant for drinking so much. Is she just wild? She is older than I am and I don't act like this so it is not a maturity thing.
