The serial killer – who murdered 13 women and tried to kill seven others – has also threatened to stop taking his anti-psychotic medicine.
But some claim Sutcliffe is faking it – in a bid to avoid a move from to a regular prison.
But the convicted killer has vowed to go on hunger strike if the move goes ahead.
Sutcliffe – who claims to be on so many pills he is like a “football rattle” – told mates he is “cracking up”.
The Sun reported him as saying: “It told me to attack, kill.
“That there were two prostitutes sat on the other side.
“Back to the old days.”
It costs £325,000 a year to keep Sutcliffe in Broadmoor – compared to only £26,000 at Wakefield.
