Browne says she knows what it is like in heaven. In her book The Other Side and Back, she says the temperature is a constant 78°F (25.6°C), that there are no insects–-unless one wants there to be, that pets go to heaven, and that one can build one's house wherever one wants unless it obscures the view of a river or some trees, in which case one needs permission. She asserts that the "other side" exists approximately three feet above ground level and at a "higher vibrational level" and so is difficult for humans to perceive. However, like other psychics, she claims to have been born able to perceive a wider range of "vibrational frequencies".
Browne declares that she can see angels and that they look similar to depictions in paintings, but have different traits depending on their "phylum". She has also claimed that they do not speak. Her granddaughter, who is purportedly psychic, claims to have witnessed the angels that Browne states surround humans.
Browne professes the ability to speak with her spirit guide, "Francine," and has given details of fifty-four of her own former lives as divined by her.
 Introduction to predictions
Wikiquote has a collection of quotations related to: Sylvia Browne
Although Browne has made many public predictions, according to James Randi her accuracy rate has been no better than educated guessing. Her predictions include: that Bill Clinton was falsely accused in the Lewinsky scandal (proved incorrect); that George H. W. Bush would defeat Bill Clinton in the 1992 U.S. presidential election (Bush lost); that Bill Bradley would win the 2000 U.S. presidential election with the Reform Party coming in second; the "hiding in caves" of Osama bin Laden and Saddam Hussein (found in a spider hole in the ground); the death of bin Laden (later reported by the Central Intelligence Agency as incorrect); a verdict of guilty in the 2005 child molestation trial of Michael Jackson (Jackson was acquitted); and the cure and prevention of breast cancer by the end of 1999.
Janet McDonald, an author of books for young adults, describes her experience receiving a psychic reading via phone, for which she paid Browne $700. Browne predicted a "really long life" for McDonald, who died of cancer at 53 just over four years later.
In 2005 Browne told Newsweek that Larry King, a believer in the paranormal, has asked her to perform private psychic readings.
On September 3, 2001, Browne stated on Larry King Live that she would accept the James Randi Educational Foundation's $1,000,000 challenge to demonstrate supernatural abilities in a controlled scientific test. As of 2009[update], Browne has claimed that she has found it increasingly difficult to contact the Foundation or respond to Randi's enquiries.
A January 2007 episode of Anderson Cooper 360 featured Linda Rossi, Browne's business manager for 35 years, and James Randi. Randi proposed that Browne undergo a test where she would provide readings for ten sympathetic people, each of whom would then identify their own reading among the ten. Rossi declined on Browne's behalf.
Of her predictions that might be considered accurate, many are predictions that are easy to make. Examples from her list of predictions for the 21st century include: "Elizabeth Taylor ends up back at the Betty Ford Center"; "Neither Warren Beatty nor Donald Trump has any success in politics"; "Air travel reaches an all-time high, but because of overbookings and poor service, the airlines will need to revamp their scheduling practices".
