From Wikipedia
A time slip (also called a timeslip) is an alleged paranormal phenomenon in which a person, or group of people, travel through time through
supernatural (rather than technological) means. As with all paranormal phenomena, the objective reality of such experiences is disputed
One of the best-known, and earliest, examples of a time slip was reported by two English women, Charlotte Anne Moberly (16 September 1846 - 7 May
1937) and Eleanor Jourdain (1863–1924), the principal and vice-principal of St Hugh's College, Oxford, who believed they slipped back in time in
the gardens of the Petit Trianon at Versailles from the summer of 1901 to the period of the French Revolution.
On August 10, 1901 Moberly and Jourdain were visiting the Palace of Versailles. They decided to go in search of the Petit Trianon. While walking
through the grounds they both were impressed by a feeling of oppressive gloom. They claimed to have encountered, and interacted with, a number of
people in old fashioned attire whom they later assumed to have been members of the court of Marie Antoinette and to have seen a figure that may have
been Marie Antoinette herself on the day in 1792 when she learned that the mob had stormed the Tuileries Palace.
The Vanishing Hotel
A widely-publicised case from October 1979, described in the ITV television series Strange But True?, concerned the Simpsons and the Gisbys, two
English married couples driving through France en route to a holiday in Spain. They claimed to have stayed overnight at a curiously old-fashioned
hotel and decided to break their return journey at the same hotel but were unable to find it. Photographs taken during their stay, which were in the
middle of a roll of film, were missing, even from the negative strips, when the pictures were developed.
Bold Street, Liverpool
In recent years, the street has gained an eerie reputation as the location of a number of time slip phenomena in which people have claimed to travel
briefly back in time to Bold Street as it was in the 1950s and 1960s
Feeling of unreality
Many time slip witnesses report that, at the start of their experience of the phenomena, their immediate surroundings take on an oddly flat, underlit
and lifeless appearance, and normal sounds seem muffled. This is sometimes accompanied by feelings of depression and unease. In some respects, this
facet of the phenomenon is similar to the Oz Factor identified by British ufo researcher Jenny Randles in some reports of encounters with supposed
extraterrestrial craft.
Ability to interact
Reports vary as to whether those experiencing time slips can take an active part in the event, interacting with the time being "visited". In the
Versailles case, the two ladies were apparently seen, and spoken to, by people they saw. The French holidaymakers in 1979 went further, staying in a
hotel and eating dinner and breakfast in the course of their experience. Both these cases are also unusually prolonged experiences, taking place over
at least several hours.
In other cases, the subject is a passive observer of the "past" scene, and it seems that the "typical" time slip lasts only a matter of a few
minutes.
So I pose my question, is this really happening? Are people really stepping back in time? if so how has it affected history? surely someone had to
give warnings about Hitler or Ghengis Khan? Or maybe there was someone even worse but that time line was changed and we have no memory of it?
IF you look at some of the examples, reported by Tim Swartz A case from Yorkshire in the 1980s: the people experiencing a time slip have no control
over what time they visit. that one fact could drop you in a very dangerous place... as in a battle field or in the middle of the Black Plague
