There's a conspiracy theory that Prince Charles and Princess Diana have a secret daughter, born through IVF without their knowledge. On the other hand, dream analyst Joan Hanger predicted that the late Princess of Wales was pregnant before she died. Is there any truth to anything of this?

Hanger revealed to New Idea that she was in a conversation with the People's Princess three weeks before she died. At the time, the mother-of-two often dreamt of someone dark standing beside her bed.

She told Princess Diana that if she was dreaming about it a lot of times, it could mean she needed to lean on the stronger side of herself. But, it could also mean another thing; she might be pregnant.

Prince Charles' former wife, reportedly, fell off the couch when Hanger told her that. Although no child was born from her at the time, Hanger admitted that she wouldn't be surprised if Princess Diana wanted to give her kids, Prince William and Prince Harry, another sibling.

Before her divorce from the Duke of Cornwall, Princess Diana was deeply in love with Prince Charles that she wanted to have a lot of children with him. She was dreaming of having a big family in an ideal world that she liked to have with her then-husband.

Sadly, although Princess Diana wanted to do that, Prince Charles wasn't. She was said to be dreaming of having a daughter, believing having another child could save their marriage. Richard Kay and Geoffrey Lev said on Daily Mail that Diana thought that if they could only have a child -- whether a girl or a boy -- their marriage might have been saved.

Meanwhile, there's a conspiracy theory that Prince Charles and Princess Diana have a secret daughter. Allegedly, before Diana joined the royal family, Queen Elizabeth II had her fertility tested before she got married to her heir to know if she could give him kids.

Rumors have it that the doctors harvested Princess Diana's eggs that successfully fertilized with Prince Charles' sperm. After that, the doctors were ordered to destroy the embryo, but one of them didn't do so.

One doctor, allegedly, held one of the embryos and implanted it in his wife, who had no idea she became Prince Charles and Princess Diana's surrogate and gave birth to a baby girl in 1981. The former royal couple's alleged daughter was named Sarah.

Sarah's parents were said to be dead after a car accident, and she learned about her real identity through a diary. She, reportedly, searched for her real mom and dad, who was Prince Charles and Princess Diana, but she received a threatening message, saying she should stop looking.
