It is enough to give even the most sceptical of bar workers food for thought regarding the existence of spirits of the non-drinkable variety.
Gary Hayley, owner of the Lime Bar nightclub at No.1 Witham, close to Lime Street and the River Hull, says his staff have been left terrified by unexplained goings-on.
Now, they have called on the expertise of Hull PSI in a bid to get to the bottom of the mystery.
"We have also seen some shadows and one night three of us were standing in the bar at 3.30am, after we had closed, and heard the door bell ring.
"We checked and it was not connected to a power supply."
Mark Lindsay, a member of Hull PSI, made an interesting discovery about the site.
"I uncovered a tragic accident that killed several people," said Mr Lindsay.
According to newspaper reports of the day, a warehouse, which once stood close to where Lime Bar is today, collapsed on Friday, September 25, 1868, killing eight people.
Coverage of the tragic accident made headline news across the country, as well as the Hull Packet and East Riding Times – a pre-runner to the Hull Daily Mail.
Our predecessors stated other reports had been "considerably exaggerated", but there was no taking away that it was a serious accident.
The Old Sugar House, as it was known, was used by Messrs Walker and Smith to store linseed, according to both articles.
Mr Lindsay said: "The articles give considerable detail regarding the hours before the collapse, the falling of the building and the rescue attempts made throughout the afternoon.
"The inquest on the eight who died, one of whom was a six-year-old boy who had just been passing the building, concluded that the collapse was caused by the overloading of a building already weakened by decades of subsidence of the pillars and foundations that held the lower floor.
"Is this building haunted by the people who died in 1868?"
Built in 1731, the building was the first prominent structure that met the eye of a person entering Lime Street.
Its dimensions, according to the newspaper report, were 79ft in length, 46ft in breadth, and 74ft in height, with 138 windows.
Mr Lindsay said: "There have been several contradictory statements with regards to the number of persons present at the time of the accident.
"But it seems pretty certain that there were about 20 men and boys in the building."
The London paper states a five-year-old boy was among the dead, but there is no mention of a child fatality in the Hull paper.
Mr Lindsay said observations made during a recent, preliminary investigation at Lime Bar would merit another visit.
"When I was at the building, I took electric and magnetic readings," he said. "All fluctuated around the building."
The Hull Packet and East Riding Times report, which describes efforts to rescue the stricken men, carries the headline, "Dreadful Calamity In Lime Street".
It stated: "It would appear that, at about a quarter past eleven, seven coopers were at work in the cooperage, which is on the ground floor of the building, when a tremendous crash was heard, followed immediately by a downfall of bricks, linseed and debris."
Some of the dead were named as Francis Harrison, 27, James Woolsten, 55, George Gilliard, 30, and William Watkinson, 25.
Mr Hayley said he is eagerly anticipating the results of the in-depth investigation.
"It's little things that are bothering us. It's not a nasty presence," he said. "It's more intriguing and we would like to get to the bottom of it."
