Former nurse Kerrie-Ann Thornton, 37, says her first encounter with an extraterrestrial took place when a dark figure suddenly appeared from the back seat of her car as she was driving on a Sydney highway.
"From then on it kept happening," she tells news.com.au.
"It made my life hell until I actually learned to communicate with them and then it settled down. "And eight years later here we are."
Ms Thornton now dedicates her life to serving ''the greys'', which are the "peaceful alien species" she claims to have a contract with.
As a self-professed psychic medium and telepathic communicator, she says she also has contact with other alien races including the Draconians, Reptilians, Annunaki and Illuminati.
Ms Thornton, from Harrington Park, is one of thousands of people around the world who believe in the existence of these so-called extraterrestrial creatures which she claims talk directly to her.
She says the purpose of the communications is so the aliens can pass on messages about living and dead people and animals to "help us".
While some people might call Ms Thornton and her beliefs crazy, she insists she, and they, are not.
"If you want to call me crazy, or I'm just making things up, or an attention seeker, go right ahead," Ms Thornton says.
"It's not my business.
"My job and my business is to deliver messages for the ETs ... it's up to you what you do with those messages."
About 12 people, men and women, pay a $20 entry fee and file into the small function room to watch Ms Thornton become possessed by aliens and deliver messages to them on a sunny Sunday afternoon in March.
They meet in an old country-style motel, tucked behind a used car sales business in Campbelltown, on the outskirts of western Sydney.
"You are invited to ask questions about anything, the ETs themselves, life, the universe, etc and the ETs will answer all questions," a pamphlet advertising the seminar reads.
No "security sensitive" questions are allowed. It's in the best interests of the human race, Ms Thornton says.
It's the first time Ms Thornton has attempted to lend her mind, body and soul to the aliens she claims to have been communicating with telepathically and in person for almost a decade. She says the aliens will possess her to deliver important messages to earthlings.
She says she has been preparing her body "mentally, spiritually and physically" for this moment for seven years.
She warns that "everyone will be running for the door" in the second half of her seminar when she becomes possessed or if the aliens decide to appear in the room.
"I'm told they're going to put on a big show," she tells news.com.au.
"They're calling it 'the Awakening'. They're going to make a statement.
"I won't remember the second half after it's happened."
Guests are told there is nothing to fear and advised not to be alarmed if they "feel something touch [their] shoulder" or if the medium starts levitating.
"There are 30-plus ETs in this room right now ... invisible," Ms Thornton says.
John Farnham's You're the Voice starts playing on a small radio at the front of the room. Ms Thornton looks at guests in the front row and tells them: "not my choice".
"You ready guys?' she asks the invisible ETs.
MESSAGES FROM "INVISIBLE ETs"
Ms Thornton starts the seminar by giving audience members individual readings she says come directly from the other worldly entities.
She tells one audience member that her dead grey cat didn't like the Whiskers meat she fed it and would have preferred the Kitty Kat brand.
Another woman is asked who "the young child who fell out of a tree and broke their arm" was. She says she has no idea who the psychic is talking about.
Ms Thornton: "Tell him to keep a check on thermometer as it's faulty and you'll wake up with fried fish."
She then turns her attention to another young woman in the audience.
Ms Thornton: "You're having internet trouble."
Guest: "No."
Ms Thornton: "Okay it might be coming. Just watch your internet server, [the provider is] going through issues."
After a short break, tea and biscuits, the second half of the seminar gets under way. This is where things are expected to get especially interesting as Ms Thornton attempts to allow aliens to take over her body. It's the moment guests were warned they might run for the door.
She takes a swig of water and shakes her hands like an athlete preparing to compete. She stares intently at the ground, awaiting for something phenomenal to take hold. Nothing happens.
So she fills the time instead by relaying second-hand messages from the alleged aliens.
TRUMP, KATE & WILL, AND THE QUEEN
Talk turns to celebrities, royals and politicians and which of them are supposedly aliens or hybrids.
"Is Queen Elizabeth a clone?" one guest asks.
Ms Thornton: "No, she's not."
But the same can't be said for Kate Middleton, according to Ms Thornton.
"His only interest is gaining technology, gaining power, gaining money and wanting to take over the world, and this is driven by his ties to Putin and the Illuminati."
A member of the audience raises his hand.
"What is Pauline Hanson?" he asks.
Ms Thornton: "A few people have said she's an alien but she is not. She is someone with morals and integrity."
'WHY I WAS CHOSEN'
Ms Thornton tells news.com.au she sees the aliens through her "third eye and physical eyes".
She describes the "typical grey" as being about seven-foot (2.1m) tall with "large heads, black eyes, small nose and mouth, skinny necks, long slender bodies and very muscular".
As the three and a half-hour session comes to a close it becomes apparent Ms Thornton's attempt to become possessed by aliens has not worked. Not today. Her seven years of training for the moment has apparently all been in vain.
"I think they have not done that because they have not got their message across," she tells news.com.au.
"People have understood why they're here and their messages and I believe that they would have done a possession if people did not believe, if they were challenging what they said."
News.com.au reminds Ms Thornton that many sceptics will read this story and not believe her claims.
But according to Ms Thornton, that doesn't matter because all will be revealed later this year.
"They will be showing themselves in the next couple of weeks and months," she says.
