The Neighbours cast member, played by Zoe Cramond, started off the episode by having a raunchy dream about teenager Jayden Warley.
She could be heard moaning: "Scrub harder, so soapy. Hose it off," while writhing on the sofa.
Poor Amy was left very embarrassed as she was interrupted by Mishti Sharma (Scarlet Vas), who heard the noises and woke her up.

Clearly realising that she had slept with someone, she grabbed her clothes and legged it.
After her attraction to schoolboy Jayden became clear, fans came to the conclusion that he was the person who she had the night of passion with.
They took to social media to share their shock at the pairing, as Jayden is only a few years older than Amy's own son Jimmy.
One posted: "Amy?! He is way too young for you."
Another added: "Sorry but Amy writhing around on the couch while dreaming about Jayden was too much. Jayden is only a few years older than her son."
A third chipped in: "Steph dating Jack, Sheila dating Clive, now Amy being attracted to Jayden. What is it with all of these women going after men young enough to be their children."
Meanwhile, fans have also speculated that Amy's dad Paul Robinson (Stefan Dennis) is secretly Jayden's father, after he slept with his mum Sue Parker off-screen.
Has Amy just had relations with yet another brother?
She shocked viewers last year when she nearly slept with her secret half-brother Leo Tanaka (Tim Kano), before his secret identity was revealed.
Neighbours continues tomorrow at 1.45pm on Channel 5.
