Come across a few in my time.The first when I visited the boarded up home of Dr.Buktyar Rustomi (Buck Ruxton) as he became.
He's the guy who killed his wife and maid, cut up the bodies and dumped them in a ravine in Scotland.The women still haunt or at least did when I went there the house and surgery in Dalton Square Lancaster.

Second one was the White Lady from Salmesbury Hall.Don't know anything about her except I nearly crashed the car I was driving.
There were two at Spring Hill club one used to turn the gas cylinders off and continued to do so for years after I left,the other just seamed to look around now and again.
Strange thing they were all white,why do you never see a black one?
