David Simcock is aiming I'm A Dreamer at the Betfred Middleton Stakes at York on Thursday 17 May.
The five-year-old daughter of Noverre features among a high-quality entry of 22 for the £100,000 Group 2, which was won last season by six-time Group 1 winner Midday.
I'm A Dreamer won on her seasonal reappearance last season when taking the Group 3 Dahlia Stakes at Newmarket in emphatic fashion.
She then went on to finish fourth in the Group 1 Sun Chariot Stakes but arguably her best effort came last autumn when going down by just a head in the Grade 1 E P Taylor at Woodbine, Canada.
Simcock has been pleased with her progress over the winter and is looking forward to campaigning her over a mile and a quarter this season.
He said: "I'm A Dreamer is almost our flag-bearer in that she is the only real proven quality horse in the yard.
"She is in the Middleton and the plan is for her to have her seasonal bow at York. But at the moment she is not being trained particularly hard as the race is still quite a long way off.
"She is enjoying her canters at present and hasn't been asked any serious questions so far this spring.
"To finish second in the E P Taylor was a great run - she enjoyed the step up to a mile and a quarter. She is a big filly who we are hoping for a good year with - and it could be that she is campaigned in America during the second half of the season."
Darley Yorkshire Oaks runner-up Vita Nova, trained by Sir Henry Cecil, may return to the Knavesmire for the Betfred Middleton Stakes. Fellow Warren Place inmate Timepiece - winner of the Group 1 Falmouth Stakes last July - has also been entered, while another intriguing 'possible' is the Roger Varian-trained Nahrain, winner of last year's Group 1 Prix de l'Opera.
