An award-winning journalist who moved into a house of addicts to research drug dependency has detailed his transition from observer to participant after spiraling into ice addiction himself.
Luke Williams, from Melbourne, started using drugs when he was 17 and even completed a stint in rehab before deciding to move in with two friends who had an ice addiction to research a book.
Three months into his social experiment Williams started using with the highly-addictive drug and found himself trapped in a world of his own creation, unable to tear himself away from his vivid, dream-like delusions.
He described his psychosis as "the Vortex".
"The Vortex is a highly individualised and usually compulsive experience; fantasies rage through your head without the slightest bit of effort - but often these fantasies are not about yourself, your fears, or your desires, although they can be," an extract from news.com.au read.
The critically acclaimed author started seeing visions, images of people he once knew, but in a completely different context, something he saw as "a different dimension".
"People would appear in elaborate, original costumes; the valley and surrounds created themselves, conversations began, and plots thickened," Williams wrote.
"The more I willed it, the more I wanted it, the more I brought my ego into it, the less vivid and self-generating it became."
His housemate started to reveal the sexual nature of his own visions, which started to seep into Williams' illusions, leaving him a permanent voyeur in a self-made "rolling movie of crazy, hot, sex".
"The Vortex, it seemed, had grown a libido, and the images even had a Fantasia-like quality, featuring me performing as a sexual champion with various lost and unrequited lovers," he wrote.
He said the visions showed him a reality he yearned for - a side of himself that he wanted to be, but never could.
"The 'movies' just kept getting better, and I couldn't stop watching them: for one thing, it felt as if I wasn't actually in control of them or of anything I was doing."
Williams realised his vivid, dream-like psychosis started to take hold of his life when he found himself masturbating for a 16-hour period.
He then tried to decrease his dosages and focus on using the drug to heighten his creativity, which at some times made him feel invisible or extraordinarily talented and others resulted in paranoia or invasive feelings of others judging him.
