Anne Heche is infamous for her alien encounter. In 2000, Heche was discovered wandering around Fresno, California in nothing but a bra and shorts after reportedly knocking on a stranger's door to ask about a gateway to outer space. When Barbara Walters asked about her bizarre breakdown, Heche admitted that she created another personality for herself in her mid-20s named Celestia, Jesus Christ's half-sister who was from the fourth dimension and could see into the future. We couldn't make that up if we tried.
